I'm not big on passing along links and stuff, because I see so many already here, but I couldn't resist. This one is REALLY cute if you're out of work.
(And for those who care - my recent unemployment is about to come to an end after about 2 and a half weeks I think. The downer is it's gonna take two hours to get to work. But hey - I guess this is what they call character building or something.)
Anyway, give it a look. Probably best if you're on a cable modem or you're gonna be waiting for awhile.
The unit I currently use is a lot like the Klingon War Vessle that the Star Trek guys used to go back in time to save the whales. It works, but has no sound, cannot handle video, has extreme delays, etc etc.
