Hope Apple doesn't try to own "fingerprint sensors in phones". Pretty sure the tech is up for grabs? I like my Galaxy S4, but I wouldn't mind easier phone unlocking. Even better than fingerprinting, I wish I could draw an unlock pattern in the shape of whatever I wanted, a higher resolution pattern with visible brushstroke. Subtle unlock patterns would then be possible. You'd need a good algorithm to allow some difference in the reproduced pattern, while remaining high resolution enough to provide thousands more combinations than 4 digit pins. Paint to unlock - that's what I need, if anyone wants to make that as an app for Android, I'd buy it for a dollar!
