Incredibly, this is the seventh year of the D: All Things Digital conference.

We feel very lucky to get here, especially in the midst of what our own site’s Digital Daily scribe, John Paczkowski, has so perfectly dubbed the “econalypse.”

Ironically, Walt Mossberg and I planned to launch the very first conference in the middle of the last major downturn for tech, in 2001. But, in the carnage of the Web 1.0 meltdown, we actually held off for two years, with our first D gathering taking place in 2003.

It’s been a real winning streak since then for D, due in large part to our great speakers–such as Microsoft (MSFT) icon Bill Gates and Apple (AAPL) legend Steve Jobs.

Both have been onstage many times over the years, including a historic interview the pair of tech titans did together in 2007 at D5.

Other amazing speakers have included: Howard Stringer of Sony (SNE), Barry Diller of InterActiveCorp (IACI), legendary director George Lucas, Time Warner (TWX) CEO Jeff Bewkes, Jeff Bezos of Amazon (AMZN), former eBay (EBAY) CEO Meg Whitman, News Corp. (NWS) head Rupert Murdoch, Microsoft head Steve Ballmer, Walt Disney (DIS) honcho Bob Iger, Bobby Kotick of Activision Blizzard (ATVI), CBS (CBS) CEO Les Moonves, Democratic and Republican pols like former Vice President Al Gore and Sen. John McCain, all the leadership of Google (GOOG) and many, many more.

We have had a lot of great moments onstage with all these tech and media players over the years, to be sure, with interviews ranging from the funny to the sublime to the truly disastrous.

But, like the digital industry and the innovation our conference focuses on, we also like to lean forward to try to figure out what the Next Big Thing is around the corner, whether it comes from Silicon Valley or not.

That’s why we’re kicking off our conference on May 26 with two of the founders of Twitter–Biz Stone and Evan Williams–who are riding high on tech’s latest hot thing, which might turn out to be either a rocket ship or a shooting star.

They’ll be followed up over the next two days by a plethora of interesting players, from the leaders of several major mobile companies to content execs hit hard by fast-moving digital forces to a new Internet leader like Yahoo (YHOO) CEO Carol Bartz, who is trying to turn around one of the Web’s great icons from its more recent lackluster path.

And, as we always do, we will be featuring a spate of demos too, trying to see if we can unearth that next next thing.

In the past, the D stage has seen the debut of start-up products like Sling Media’s Slingbox, Aliph’s Jawbone and Pure Digital’s Flip, all of which have gone onto glory. And also some, like Palm’s Foleo, which did not.

While not everyone can attend D, our crack staff is committed to bringing all the action from this year’s conference to readers of the All Things Digital site via up-to-the-minute blogs, photos, videos, tweets, digs and more. We’ll also, as soon as we can, post the videos of each of the onstage sessions, in their entirety.

In an article in yesterday’s Wall Street Journal about an alliance being discussed between Facebook and Nokia, came news about the pair working on a deal to deeply integrate the hot social network with the handsets of the world’s largest maker of mobile phones.

Although BoomTown has seen this movie before–a similar mobile deal with a Nokia (NOK) investment in Facebook was being bandied about a year ago–expect more noise than ever when it comes to social-networking sites and mobile devices in 2009.

As you can see from the chart below, Facebook ran past MySpace in the number of unique visitors via mobile phone in the early fall of 2008 and kept climbing.

Said the Journal article: “In December, Facebook had seven million U.S. mobile users, compared with MySpace’s 5.7 million, according to Nielsen Co.” (Full disclosure: MySpace is owned by News Corp. (NWS), which also owns Dow Jones, the owner of this site.)

And, indeed, to get this kind of traction, Facebook has been very busy ferreting away to get a presence on all the big cellphone makers, so far mostly by building its popular Facebook application for smartphones like the BlackBerry from Research in Motion (RIMM) and iPhone from Apple (AAPL).

Facebook–the Journal piece said–has also been talking to Palm (PALM), which will launch its new Pre smartphone in the spring, and Motorola (MOT), about being integrated into their operating systems too.

The race to be present on mobile devices by everyone and their Internet mother has gotten all hopped up with the introduction of so many smartphones of late, since these devices make any Web app experience much better.

And consumer uptake of these kinds of phones, with big screens and multitouch capabilities, is widely expected to dramatically increase over the next five years,

But here is the dicey money–or nonmoney, actually–quote from the article:

“As with most of the cellphone-software industry, Facebook has yet to find a way to generate meaningful revenue from its mobile services, which include text-messaging features, a mobile Web site and downloadable software. But the number of users accessing its site from phones has grown.”

Oh dear–that roughly translates in Facebook-speak to friending without benefits, with costs rising without much (or any) revenue coming in, to speak of.

Of course, many would argue that both Facebook and MySpace, as well other big players, have to still play hard in the mobile market to gain users–given that consumers are on the move more than ever, digitally-speaking–even if it takes a while to see financial results.

So while efforts by mobile advertising services, such as AdMob, are trying to make that happen and are definitely promising, it’s still a game of growth and not revenue or, of course, profits.

BoomTown did a video interview with Palm’s sugar daddy investor Roger McNamee at the Consumer Electronics Show last week, after the debut of its Pre smartphone.

Via Elevation Partners, McNamee has invested a total of $425 million in Palm, aimed at reviving the company that pioneered the smartphone market.

But Palm soon saw its business gobbled up by the BlackBerry from Research in Motion (RIMM) and the iPhone from Apple (AAPL). And, of course, there is the G1 phone from Google (GOOG) too, along with competition from Nokia (NOK) and many others.

And Palm is following the less-than-stellar last launch of the Foleo in 2007.

Thus, the company and the private equity firm have banked a lot on this revival, so McNamee was out in full force at CES in Las Vegas, talking up the Pre.

The Pre launch was indeed the highlight of the show, and also gave Palm’s moribund stock a boost.

And, indeed, the Pre does look pretty cool, with a sleek design and a new operating system, although the real proof will be when it debuts to consumers later this year.

In any case, here is the always hopped-up McNamee giving it his best for the Pre:

Hello, my name is BoomTown and I am a reformed CrackBerryaholic.

How bad was it? Here’s the worst story: I was holding my BlackBerry in my hand, inadvertently for once, when I gave birth to my son in 2002.

Long story short: I was emailing away throughout labor, suddenly had to have emergency surgery, was quickly drugged into paralysis and forgot it was gripped in my hand–all until the anesthesiologist looked at me like I was a freak.

I should have been embarrassed by that. I was not. Hence, that makes me a full-fledged Blackberry addict.

Actually, I was one.

Because over the weekend, while casting about for a good New Year’s resolution (Work less? Nope! Exercise more? Double nope!!), I impulsively decided to dump what is pathetically one of my more satisfying and reliable relationships ever for a questionable new one.

That’s right, I have finally abandoned the BlackBerry for the iPhone.

I have no idea what possessed me, but suddenly I had to change dramatically and change now. (I could blame the influence of fellow CrackBerry user President-Elect Barack Obama for that mood.)

So, I finally made the dreaded switcheroo from the devices made by the fine folks at Research In Motion (RIMM), which I have used since the first stubby little block of greyish plastic until the last stubby bigger block of reddish plastic.

To be honest, I have been flirting with the idea of leaving my longtime love for a while now.

Almost sneakily, I bought an iPhone from the get-go when it came out from Apple (AAPL) in June of 2007, because it was just too cool a device to pass up.

I was instantly delighted by the touchscreen swooshing and squinching, its breakthrough quality as a handheld media player, the Internet access that finally worked and the generally clever way of organizing contact and other information. I also liked the voicemail recording a lot.

Not so much the AT&T (T) cellular network, of course, but that was livable. What was not, as it was for a lot of people, was the poor email experience, specifically the virtual keyboard.

To say my entire life revolves around email and texting is to go overboard. But not by much. It is, in fact, the bane of my partner, who has learned to live with it grudgingly.

My obsession has even turned into mimicry by my other son, a three-year-old, who grabbed a small and rectangular block of wood recently and started tapping on it with his fingers, proudly declaring, “I’m Mama working!”

Oh dear. Like I said, I am pathetic in this regard (on the plus side, I don’t drink, do drugs or watch “Dancing with the Stars”).

But my issues with the dullish BlackBerry slowly mounted, from its too-small screen, to the substandard Internet experience to the limited ways to store emails to the overall clunkiness of it.

And when the apps came out for the iPhone, it got worse, since the ones on BlackBerry just are not as robust at all.

And with those apps, I now did not even have to really launch a browser and click away in frustration. Instead, I could largely rely on an increasingly interesting array of software that made my digital life a lot easier.

I am not including the iFart app in this group, of course, the kind of toddler programming that I had thought I had left behind when I started ignoring Facebook apps. Verdict: Eww.

In any case, my BlackBerry still had those lovely clickety-clack keys that have always been a joy to press and with which I could write a book in a very short time, I had become so adept at using them.

So, I had great hopes for the BlackBerry Storm, with a clicking-like virtual keyboard, as the solution to all my problems. Or so I thought.

When I first saw it, I knew this was not what I had been waiting for, which was underscored by Walt Mossberg’s review.

The weird push on the glass screen made me feel like it was going to break with every click. What I really wanted was the tactile feel of the keys and not the click feel.

The G1 smartphone from Google (GOOG), of course, offered a real keyboard and the big touchscreen. But it just looks and feels too much like–let’s be honest–a pair of clogs I once wore in seventh grade and have regretted ever since.

And, while there is a Palm device reportedly coming out this week with a touchscreen and a slip-down keyboard, I guess I have finally become tired of waiting for something that is perhaps not possible: A virtual keyboard that feels real.

Thus, I gave into the iPhone and learned to live with my all-thumbs typing.

And, as many have said, I am actually getting better at that. Not speedy, as I was with the BlackBerry, which–ironically–has caused me not to use the iPhone as obsessively and to put it down a lot more.

Except that, as soon as I do put it down, it is immediately picked up by my now six-year-old, the very person who had endured my incessant pregnant clicking.

As it turns out, he is obsessed with the many game apps I have downloaded for him onto the iPhone–currently “Crazy Penguin Catapult.” (Verdict: Unusually fun.)

So much so that he sneaked into my bedroom yesterday morning and spirited my iPhone away for a session while I slept late.

What can I say? Like mother, like son.

In this regard, let’s hope not.
