The recent talk of the iPhone got me thinking about interfaces in general, and touchscreen interfaces in specific. The touchscreen interface has been around for a long time, and in all its incarnations, it has always been the bastard stepchild of interfaces. Whether it is on kiosks, ATMs, PDAs, phones, or universal remotes, just about everyone has given it a go, and just about every time it has ended up being replaced with a real button, or some other physical interface.

Seems to be a question of personal preference. My wife pretty requires a touchscreen (she's using an MDA currently). I've used them (my universal remote has one), but I get tired of wiping fingerprints off my screen constantly.
