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.

Here’s the video:

Crovitz knows a thing or two about the transition mainstream media has been making to new media and, more importantly, was never scared of the change. For us, that was critical, since he consistently said yes to our efforts to create a new kind of tech site within Dow Jones.

Tonight, he appears at a Churchill Club event called “Like It or Not, You’re in the Media Business: It’s Time to Make the Publishing Upheaval Work for You.”

Other speakers include: Neil Chase, VP of author services for Federated Media; Ken Doctor, affiliate analyst of Outsell Inc.; and Jeanette Gibson, editor-in-chief of News@Cisco (CSCO). The event is moderated by Sam Whitmore, editor of Sam Whitmore’s Media Survey.

A description of the event: “Internet technology has made you a publisher. How can you turn that into a huge win for your career and your business? Well, first you might want to study what traditional publishers have learned, and what they’re doing to transform their business. After all, they ought to know. Then look at all the commercially successful bloggers: how did they do that? Then consider Cisco Systems, one of the world’s most successful tech vendors, and why it is now a successful publisher in its own right.”

It takes place tonight, starting at 6 p.m. for dinner, followed by the program at 7 p.m. at the San Mateo (Calif.) Marriott.
