Let the hive mind of Engadget get that for you.
"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
what interests me is how they got the technology so thin. typically, the iphone (and i'm guessing the lenovo laptops) use capacitative sensors (similar to your standard laptop touchpad, just with a bunch of them in a grid)
but the msft guy said that this was IR - now the IR stuff like jefferson han from nyu showed w/ the multi-touch table had a camera directly underneath and and projected reflected off a mirror on the side (i think - this is the typical FTIR table setup), but the msft guy is using an IR based multi-touch display that's pretty thin (IE no projectors involved, just a nice thin LCD)
any DIYers up to the challenge?
