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!"
The MS Fingerprint reader is pretty durable, and I think it would be possible to make the reader completely waterproof with some silicone glue to seal out the water from the fingerprint sensor area. As most of you know, the MS Fingerprint device is a copy of the Digital Persona UareU 4000b, and even though they (DP) won't confirm it, I know they've sold a large number of those readers with solid glass sensor protectors (the ones they usually use is made out of silicone). These are virtually waterproof.
We've done a multilingual Time&Assistance application called Cerberus using this tech. Not waterproof yet, though... http://www.cerberus.com.mx. The site is all in Spanish, but you can read some about Cerberus at http://www.lekare.com
