These comments are from people who wouldn't care about PDAs before iPhone.
I have big clumsy sweaty fingers and struggle even with today's big smartphones.
I was a kid back then, but those PDAs would have normal keyboards and a stylus and an OS with a UI not feeling as if it were made for asylum patients.
But that's not important, why would one even defend against really functional systems something the main features of which were "look how I can zoom pictures with two fingers on that thing", "look how cute it looks, shiny" and "look, nice icons, you'll wanna lick 'em".
