Best of Demo - the cool stuff The following products may not make you more productive or profitable, but I liked them just because they're so cool.

eVoke TV - This service combines community media and TV listings to create an entirely new entertainment experience. Evoke makes it possible to link the TV guide to the vast amounts of factual and fan-generated information on the Web. You'll be so busy navigating you'll miss the show. Oh, right, that's why you got...

Digital Deck - This could be the evolution of TiVo but the price has got to come down. Digital Deck makes it possible for every media device in a home to attach to every other media device. So the TV in the kids' room can play a show recorded from the cable box in the living room. By designating one PC as, essentially, a network server, all the media is cached centrally for delivery to connected devices. However, Digital Deck recommends hard-wired Ethernet connections and will charge $800 for a basic two-room system when the device ships in April. That's just too high.

Kaboodle.com - I always through the epinions.com concept - let users recommend products and services to others by voting for their favorites - was a great idea that no one ever figured out how to deliver. Kaboodle is the Web 2.0 version of that. You research a purchase and share your findings with others. As the community grows, the quality of information gets richer. Is it finally time for this idea to take root?

Polyvision's Thunder Enterprise Collaboration System - We've all been in training sessions where flip chart pages get scribbled on and pasted all over the walls. Polyvision has done that in software. The flip chart in this case is a large, touch-sensitive flat panel screen and up to 12 completed pages can be ''torn off'' and displayed simultaneously on walls via ceiling-mounted projectors. Pages can be easily moved around and edited and the whole thing saved digitally. You can also share the whole experience with remote users. This product is way cool, but I've got to wonder how many customers will be willing to pay $100,000 for a fully installed system. Paper and masking tape always worked pretty well for me.

Vivid Sky LLC's SkyBox - As a baseball nut and statistics freak, I'm always wishing I had more information available to me when I'm at the game. SkyBox is a ruggedized, handheld computer that gives fans access to statistics, replays and even concession menus from their seats. In theory, you could get ESPN, ESPN.com and an interactive stadium guide in a PDA. It's a great idea but the devil is in the details. Vivid Sky foresees sports teams renting the little units to attendees for $10 or $20 a game but hasn't signed any customers yet. And I wonder how the umpires are going to like that instant-replay-on-demand feature? Nevertheless, if this product comes to be, I want one.

Zinkkat, LLC's Chili - Chili is a banana-shaped device that fits on a teenager's belt or baggy pants pocket and delivers audio content from any Bluetooth-attached computer. The user can chat on Skype, play MP3s, listen to Internet radio and access e-mail through a text-to-speech interface. At $150, it'll be affordable and it's cool to look at.

MooBella, LLC - The longest lines at Demo snaked from the MooBella exhibit, where two refrigerator-sized machines churned out made-to-order ice cream every 45 seconds for sugar-craving attendees. The machines are technological marvels; the whole freezing, mixing and deliver process is done in real-time while the customer waits. The target market is food service providers like college cafeterias and hospitals. The fact that this company has raised $36 million in venture capital shows that even mature markets can spark innovation.  ¶ 9:05 AM
