Way back in the fall of 2001, when BoomTown was but a less-aged version of myself, I attended a keynote speech at the now-defunct Comdex show in Las Vegas, where Microsoft Chairman Bill Gates continued to bang the drum for one of his long-running obsessions: The tablet computer.

“The tablet takes cutting-edge PC technology and makes it available whenever you want it, which is why I’m already using a tablet as my everyday computer,” Gates said at the time to the audience gathered at the MGM Grand Garden Arena. “It’s a PC that is virtually without limits and within five years I predict it will be the most popular form of PC sold in America.”

Well, that did not happen.

But Gates did keep his promise about using a tablet–he kept on doing so and also harping on the topic all the time, with Microsoft even releasing a giant tabletop Surface several years ago and supporting multitouch in the coming Windows 7.

I recall Gates talking about the idea of how important the tablet is on innumerable occasions, more than any single concept I can recall.

It is ironic, then, that all the hype has suddenly and firmly coalesced around the particulars of the tablet that Apple (AAPL) will be unveiling in the coming months.

And now that CEO Steve Jobs is back fine-tuning the whole shebang, the obsession has moved into overdrive, punctuated only by endless stories about every single new app for the iPhone and fights over some of those new apps for the iPhone.

It’s a complete aside, but how ironic is it that Apple has somehow managed to make Google (GOOG)–the Skynet of the Internet–seem like a victim over this Google Voice shrillathon?

Back to the Apple tablet, which is playbook hype for iconic computer giant.

Besides being a secret project everyone in Silicon Valley seems to know about, the coming device is enjoying full-on breathless reportage of every single possible button and every possible feature, with every single bit of functionality parsed, dissected, masticated and spat back out.

But let’s be honest–in the end, this Apple tablet is probably going to be some kind of giant, sleeker, more glorified and doubtlessly niftier version of the iPod touch, called the iTab or the iPad or the iAmSoCoolAren’tI?, at three times the price.

Now, as it turns out, Microsoft (MSFT) is also at work on a table device, this time called the Courier.

This development became known recently after a demo video of it in use was somehow “leaked”–three guesses about which software giant in Redmond, Wash., put that out, and the first two don’t count!–to Gizmodo.

It seems to be some kind of tablet mixed with a journal mixed with a day planner, with a hinged two-page look. Digital writing and a stylus are involved, but also lots of touchscreen action.

Well, I say, good for Microsoft, and perhaps for Gates, who has now mostly disengaged himself from the day-to-day particulars of the behemoth he built, including the Courier.

Nonetheless, in all likelihood, Apple will still garner the most buzz in this tablet faceoff and will, more than likely, sell more.

A delicious irony, given that in their fascinating and long-running rivalry, it has usually been Jobs playing the hopeless dreamer and Gates the one who makes bank from the dreams of others.

No longer, which should make this round between Microsoft and Apple the most interesting of all.

Speaking of dreaming of dreams, it is always a good time to post the video of Susan Boyle singing “I Dreamed a Dream”:

That’s not to say it’s a particularly good or bad idea to hire a former Dreamworks and Wal-Mart (WMT) exec named David Porter (pictured here) as vice president of retail stores to create Microsoft-branded stores–or as the company announced yesterday, “to create a better PC and Microsoft retail purchase experience.”

While Microsoft (MSFT) sells most of its consumer products via big-box retail stores like Best Buy (BBY), and the retail market for just about everything is weak, Apple (AAPL) has definitively proven that a well-designed retail store can be a powerful marketing tool.

The visually stunning and infectiously fun Apple stores, in fact, have been an important part of its recent surge in mainstream consumer appeal, becoming hubs of activity and even social life in its mostly big-city locations.

In fact, that was just the idea behind microsoftSF, which was located in San Francisco’s Metreon Sony Entertainment Center.

The huge 8,500-square-foot store, with 160 Microsoft products and related software and hardware from 30 partners, was billed in a June 1999 press release as “an interactive, hands-on retail environment in which people of all ages, from all walks of life and at all levels of technological expertise can explore the benefits technology can bring them. Far more than just another computer store, microsoftSF is a showcase for the latest technology from Microsoft and the hardware and software companies with which it collaborates.”

The microsoftSF store, which I visited several times (but bought nothing, although I was mostly a PC user at the time), was very attractive and the only such store in the world, with a “Road Warrior” arena, a lounge, a gaming area and more.

Said the press release: “To make all this possible, microsoftSF deploys Microsoft Windows and more than 100,000 feet of copper cable, 60 Sony PCs, 18 laptop docking stations, four dual-processor servers powered by Hewlett-Packard Net Servers, a Cisco Systems network, and an array of hidden audio speakers that create 16 individually controlled sound zones.”

And Microsoft CEO (then President) Steve Ballmer weighed in enthusiastically:

“We are delighted to be able to showcase in this one-of-a-kind retail environment the entire range of Microsoft software and hardware, as well as the technology of other companies who share the vision of how the PC and the Internet can empower people any time, anywhere. San Francisco and the Silicon Valley are home to the world’s largest and one of the most sophisticated high-tech audiences, so this was the natural place to create this site–dedicated to showing, in an interactive environment, the way technology can enhance our working, learning, living and playing.”

Not so much, as it turned out. The store closed in 2001.

But that does not necessarily mean that the new and much expanded efforts will have the same experience. The Metreon, which was sold off by Sony, was an odd mall then and still is, although its movie theater is successful.

And, in this effort, Microsoft will have control of the whole enchilada.

Plus, if well done, it is not such a bad idea to have a place–perhaps only in highly-trafficked locations in big cities–to show off its consumer wares, especially its popular Xbox 360 and other products (please, not the Zune!).

More importantly, given the disaster that has been the Windows Vista experience, it is probably a good idea to have a place to get people interested in Windows 7, especially its touch capabilities, when it rolls out this year.

Also, I still like the Surface interactive table, even if it is mocked in a popular video as a “big-ass table.”

Of course, only Apple stores have done well so far in this genre, as everyone, from Gateway (GTW), Sony (SNE), Nokia (NOK), Helio and Palm (PALM), has had rough retail experiences.

So, Porter certainly has his work cut out for him, at least judging from the press release from Microsoft yesterday:

“Defining the time frame, locations and specifics for planned Microsoft-branded retail stores will be Porter’s first order of business. The purpose of opening these stores is to create deeper engagement with consumers and continue to learn firsthand about what they want and how they buy.”

Said Porter: “There are tremendous opportunities ahead for Microsoft to create a world-class shopping experience for our customers. I am excited about helping consumers make more informed decisions about their PC and software purchases, and we’ll share learnings from our stores with our existing retail and OEM partners that are critical to our success.”

He’ll have to wait to see if the second time is a charm.

Surface actually got a demo at our D5 conference last May, but BoomTown has been partial to this very funny video spoof on the “big-assed table”:

Well, you can see him in action–and in fine form–in this video of the interview he did at D5 this year with Walt Mossberg.

Here, Ballmer talks about a variety of things, such as how to foster innovation at a big company, Windows Vista, immigration, the brownness of the Zune, even as Walt forces him to say the word “Google.”

He also shows off Microsoft’s Surface table, which debuted at the conference. (Also check out the very funny Surface spoof below the Ballmer chat.)

Here are the videos:

By way of background, D: All Things Digital, the annual tech and media conference Walt Mossberg and I host, has been sold out with a long wait list every year we have put it on.

That has meant only a few hundred people can see the interviews and also demos we do live onstage with some of the tech and media industry’s most interesting and important players and products.

The lineups have included Microsoft’s Bill Gates and Apple’s Steve Jobs, as well as Eric Schmidt of Google, IAC’s Barry Diller, Meg Whitman of eBay, Cisco’s John Chambers and many others.

And we’ve demoed stuff like the Treo when it first came out, as well as digital toilets, Wi-Fi phones and much more.

We usually post the photos and videos of the interviews and demos six or more months after they take place on a separate conference site. This year, our Digital Daily’s John Paczkowski liveblogged D5 and also posted video highlights from all of the sessions immediately on our newly launched site here.

Now, we are posting videos of every session of the 2007 conference here, in full, and we have made all our photo galleries, hosted by SmugMug and mostly shot by our fabulous Asa Mathat, public too. You can also access our videos via the site’s master player here.

Every day, I am going to highlight a different interview or demo from the conference.

Here is Ballmer:

The link to the joint interview on iTunes is here, in video and also as a podcast. This link will connect you to the Gates/Jobs interview page on iTunes, but only if you have downloaded the iTunes software. As I said, I will post links on Microsoft platforms for both downloading and streaming as soon as they are up, which should be soon.

Speaking of NPR, Walt and I did a very early morning interview on “Morning Edition” about the various gadgets that we had onstage, including Microsoft’s Surface coffee-table computer and the LiveScribe smart pen.

The Surface, of course, got a lot of play after it debuted at the conference, because it was another example of Microsoft getting more into the hardware business. And it was also significant, because the idea of computing using more mundane objects is inherently interesting for anyone with a passing interest in when we will start living like the Jetsons.

And the LiveScribe smart pen is another attempt to bridge that gap between the analog and digital worlds and even merge them. Looking over my piles of notes from two books I did, I realized I would never look at them again, and it would have been nice to make them searchable. Of course, the implications for important scribbling that needs quick finding, such as by a doctor during an exam, are pretty obvious.
