Well I'm not sure what kind of PDA you were using then, but all the Palm, Handspring and various Linux ones (can't remember what they were called) that I used worked only with a finger when you used your nail, and even then there was no telling what exact 'touch point' the screen/OS was going to use. It's much like today's TomTom devices. They are advertised as being 'touchscreen', and the UI is designed as such (with big buttons etc) but they're still a bitch to operate. I mistype at least 20% of my interactions with it, and like I mentioned I have a decade of experience with working around finicky touchscreen technology (as much as I hate to admit). I'm not saying you or anyone else wasn't able to operate a previous-generation touch screen with their finger, but the experience simply wasn't good enough to make it mainstream. For example an on-screen keyboard is/was out of the question on a Palm.
