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 got this setup lastnight, very cool--but limited in use right now.
Are there any petitions to Olympus to Open-Source the firmware for the m:robe? Currently the Linux implementation runs inside the firmware, which hurts performance and is annoying. If Olympus opened this up it could cause some very cool things to happen :)
