"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!"
That's the cool thing about being a really big company - you get the chance to make really *big* mistakes. Hopefully, the big screwups don't result in massive casualties (though I think BP is crossing the line there with their oil spill).
