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 wouldnt suggest any of you buy a alienware of any sort, you ever been on the phone with them for over 2 hours at a time and have a new $6000 computer that hasnt worked since it was shipped. I ask for a replacement and even the repair man told them to replace it and they actually laughed and this was a month old computer. Pos computer i have here.
