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!"
Personally I love my PSP.
However, I have only found 2 games which are actually best played on the PSP. One is Tony hawk. Playing that on a PC without a game pad sucks. On a PSP the control are all nice and close together and my game play improved no-end. Why don't sony take advantage and make previous tony hawk games available on the PSP. The N-gage had a Tony Hawk port which rocked, though I cant remember which one(possibly 4?) which is not available for the PSP. The only other game which is good is Wipeout, again because the controls were in the right places.
I have tried Medal of Honour(which made me feel like I was drunk when playing with the slow reaction times). Marvel Alliance just got boring once you got over the excitement of playing as spidey. TMNT, Ghost rider, and other movie spin offs were the same.
What I love about the PSP are the extra apps, most of them homebrew's. It has a decent book reader, which even reads PDF's. I can even have an SSH client for accessing the servers in work while I am in the pub. The SSH client comes with a really nifty onscreen keyboard which uses the analogue stick to move around which after some practise make typing pretty fast. Add to that the internet/music/movie/photo capabilities, you have almost a laptop stand-in(not replacement). Almost.
