I can think of several. Search for Firestone and Ford to see the recall of the tires that had a issue with the tread separating. More Personally, My co-worker had her parents brakes fail as she was parking the car AT THE PLACE SHE WORKED. went through the window and hit the atm. (we work at a BP station)

while a good idea in theory, I would suggest 3 levels of power. 5v, 12v, and 24v. 5v would work just fine off USB and could simply use a mini-b connector. I have alot of car audio toys that draw 12v and they get HOT. (xm, HD Radio)

12v for printers and routers, net-books... things that need more draw, but still not too demanding.

I have 24v in there because I have yet to see a full size laptop that draws less than 16v.

you know i think it's funny, I bought a $60 Radio shack outdoor antenna, and it works alright, but if i take a $9 rabbit ear from wall-mart (RCA if you care) I can recive digital from grand rapids michigan. considering I set this up in my mom's house on the west side of Milwaukee, I thought it was pretty cool. (on a side note, where she sits, we can get about 7 analog channels, but we get somewhere around 20 digital)
