I have mixed feelings about AuthenTec fingerprint scanners in Apple products. One on hand, I had an IBM keyboard with a scanner and it was terrible. Rarely worked right, often took 3 or more swipes, was just easier to enter my password. On the other hand, if any company would make sure the product actually works before putting it in, it's Apple. I also absolutely hate how often Apple prompts me for my password. I think I was playing a game on my iPhone the other day and I had to enter my password like 5 times over. Don't remember exactly, but it was something like once to "buy" it even though it had been bought on another device, another time to login to GameCenter or something, a couple other times to buy some coins or something. Very annoying. So if they insist on checking password so often, this is something they desperately need - and need to get working better than past hardware.
