When attending the Consumer Electronics Show in Las Vegas last week, BoomTown moderated what turned out to be a fascinating panel discourse of what was to come in the tech sector.

No, it was not a gathering of Trekkies.

The CES SuperSession panel, titled “What Will They Think of Next? Consumer Technology in 2025,” was less Jules Verne than a logical analysis of where gadgetry is headed by looking at both the past and the present.

Overall consensus: Touch screens everywhere, 3-D imaging in wide use, no device wires, ubiquitous high-speed wireless networks and more.

Of course, there were some edgier ideas, like being able to tell exactly when it is going to rain to the minute, via massive computing of weather patterns.

In addition, one of the panelists, Greg Harper, brought back what was popular in 1994, the same number of years back that 2025 is forward. Yep, he dragged out for display the Apple (AAPL) Newton and brick-sized cellphones.

The panelists were: Stephen DiFranco, VP and GM, Americas Consumer Group, Lenovo; Gregory Harper, co-founder, Gadgetoff and president, Cerberus; Len J. Lauer, EVP and COO, Qualcomm (QCOM); Sean Maloney, EVP and GM, Sales and Marketing, Intel (INTC); and Phil McKinney, VP and CTO, Personal Systems Group, Hewlett-Packward (HPQ).

Here’s the video with interviews about 2025 with all of them–and don’t miss the very funny poster at the end from Microsoft (MSFT) about its vision of the future:

Last night, Walt Mossberg and I hosted yet another annual “What’s Hot and What’s Not in Personal Technology” event for the Churchill Club.

A brief rundown of the Palo Alto gadgetfest show-and-tell: An animatronic singing Elvis freaked out my No. 1 son, Louie, who played an excellent Luke Skywalker/gadget boy for my presentation; our guest gadget geek was Twitter Co-Founder and CEO Evan Williams, who was a delight with a mini-helicopter, a flat-screen reader and a wry wit; Walt showed off the new Blackberry Storm from RIM (RIMM), the alleged Apple (AAPL) iPhone killer (maybe not so much), as well as a fuel cell and more; and our crazy gadget maven, Greg Harper, co-founder of Gadgetoff, went perfectly insane with everything from tiny projectors to a creepy probe to minicellphone towers to USB ties and eyepads.

It was a lot of fun with a packed crowd, even in this econalypse-impacting Silicon Valley.

Here is a rather longish video, which is well worth watching. Yes, BoomTown is–along with Louie and Elvis–wearing a Yahoo (YHOO) hat.

Now in its fifth year, it was called “Making a List: The Fifth Annual What’s Hot and What’s Not in Personal Technology” and took place in Palo Alto, Calif. Our guest were Marissa Mayer of Google and tech consultant Greg Harper.

Walt and I typically show off several devices we think are interesting and try to identify some important trends.

Here’s a video of Walt, Greg and Marissa at the event:

(I still am having problems with the Brightcove player, so I uploaded the video to YouTube.)

For example, Walt showed the new Amazon Kindle electronic book reader (which he did not actually like so much in his review of the device this week), as well as the new version of Sony’s e-book offering. He also showed some new cellphones that are trying to mimic the Apple iPhone. His take: Great software in consumer electronics is key this year.

I showed new robotic devices from iRobot–the new version of its popular Roomba vacuum and its new wireless gutter cleaner called the Looj. We had an actual gutter on stage, full of leaves I made my much-abused assistant Ed Daly collect from a gardener’s truck we found on a suburban street.

And every year, we’ve brought in uber-gadget geek and tech consultant Harper, who always brings in a truckload of cutting edge and sometimes freaky stuff. That included an egg-shaped speaker that dances from, of course, Japan, as well as a solar battery charger, a $400 laptop and a vanity mirror that is a Webcam in disguise. Harper posited that all devices would have to be always connected going forward.

And, also annually, we invite a celebrity geek from well-known tech companies. In the past, we’ve had Google’s Larry Page, Jerry Yang of Yahoo, RealNetworks’ Rob Glaser and Chad Hurley of YouTube–geeky guys all. But Mayer, one of Google’s top execs, proved the nerdiest with a wide range of cool stuff.

She showed off a keyboard whose keys had embedded LCD screens, a wireless rabbit, an alarm clock that can jump off your nightstand and a T-shirt with a wireless signal locator in it. She also did a demo of exactly what the new Google Android operating system for cellphones looks like. Take careful notes: It looks an awful lot like the iPhone.
