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!"
I'm sorely tempted to purchase the PSP Slim, but it seems wasteful to buy games for it and for a PS3. I've been holding off buying the PS3 because I really just want it to play Gran Turismo 5 when it comes out in October. I do see one other game I'd like which is Need For Speed Carbon. Yet if I bought NFSC for the PSP Slim, I'd probably want to repurchase it for the PS3. I wish the games were transferrable from one format to the other or they gave some sort of discount if you buy both formats. It's very difficult to make these decisions with so many great devices to choose from.
