Eleksen's fabric keyboard is just one in a chain of keyboards I've seen that are meant to be rolled, folded, or otherwise mashed into a small space for travel purposes. Now, I love technology, and I love seeing cool new innovations, but having typed on one of these, all I can say is ugh. At least from an ergonomics standpoint. These things aren't at all finger-friendly. They're hard to hit the keys on, they force your hands into awkward positions, and their compact size makes you work harder to type--tense, much? I'm sure they're fine for occasional use (i.e. when traveling), but that's what laptops originally were touted for, and now many people use them exclusively. I just can't help but cringe when I see the contorted positions we assume to type on things like this (don't get me started on text-messaging on cell phones). I have this fear that we're all going to be paying down the road in increased cases of RSIs.
I could be wrong, but for now, I'll keep my Kinesis Contoured keyboard, thank you. Even if it means packing an extra suitcase for it. =)
