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!"
"Fujitsu P1510D .... A little more money gets you a whole lot more computer."
I second that motion!
My P1510D is a true UMPC that is functioning as my main computer -- i make Access databases, websites, email, photo-art, small hobby videos, and anything else you'd do on a desktop.
It weighs only 2.7 lbs! I backpacked across Europe last summer and barely noticed I was carrying the P1510!
