Here is a thing that i like. It’s a USB drive not much bigger than a key. It holds 8GBs!
Why i like this thing: well, it holds 8GBs! And it’s not much bigger than a key. Also it’s metal enclosure is durable and the terminals, while exposed are also really durable and will hold up just fine while jangling about in your pocket. I’ve split mine into 2 4GB partitions, one with a bootable image of the Ubuntu 9.04 beta, and the other for just holding stuff. It’s available for $30 for the 8gig version and it’s money well-spent if you ask me (LaCie store). Now i’m just looking for an excuse to boot any computer i meet off my keychain.
