I was thinking about buying an iCurve (or something similiar) for my Powerbook G4 12in to help keep it cool. But, I don't have an external keyboard, nor do I want to put down the cash for one right now. I saw on Griffin's website that you "can" type on an iCurve, but I was wondering if anyone had actual experience typing on an iCurve or similar product. Is it realistic to do this long term? Thanks!
