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!"
Thin = easier to break.
If you want a thin laptop expect it to die early and often. And when it comes back from being fixed, it will die early and often.
I used to be a field service engineer for DEC/CPQ/HP's contract clients, and I hated working on the thin laptops. The mainboards were so thin they were see-through, and they would sustain damage just by installing them if you were not extremely careful. Given that often I was doing laptop repairs in front of the person who used it, I always took the time required to do it perfectly. There's nothing worse than going out 5 weeks later and doing another repair in front of a person who's cranky with the last repair. On average, I'd take 45 mins to an hour. The guys in the service centre used to bang out the same job in 15-20 minutes, and in 2 months the laptop would be back.
So, go for thin all you want. Just be aware there are trade-offs in reliability, and make sure you upgrade your warranty. I'll say it again - UPGRADE YOUR WARRANTY.
