Here's an example of how electronics should work. The USB Data Transfer Device (talk about calling a spade a spade) connects two computers together with zero hassles. Just jack one USB 2.0 plug into the each PC and within seconds you'll be zipping files between them to the tune of 25 Mbps, all without installing any software. The entire contents of each PC can be seen from the other, so transferring is as easy as dragging and dropping — no network ports, no passwords, no sneakernet. It's not Mac-compatible, but if you've got a couple of Windows machines, this small wonder (3.7 x 2.7 x 0.75-inch) can can get them talking to each other for just $50 from ThinkGeek. —Peter Pachal
