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'm sure Multi-Touch will get smudged and oily, but maybe not as quickly as we assume. My mommy taught me to wash my hands whenever I use a bathroom which is probably why my touchpad doesn't get that bad (the biggest threat is muffin crumbs at Starbucks!). MT has so much potential for music software, photo editing, graphics, even gaming, and it can also display adjustable QWERTY for the right applications. You place your hands in a comfortable position on the display, and there's your perfectly sized, ergonomically shaped keyboard!
