I don’t know, I remember them being great from a HW point of view (I had an iPAQ 514 and it was mindblowing even without touch and just a tiny screen), but UX wise…

I now have another iPAQ with a stylus and touchscreen, and I’m grateful back then I did not have it nor the mobile version of Age of Empires… it’s addictive stuff and a crazy good port. I don’t remember anything so good on PalmOS 5 (we had a Garmin iQue 3600, with integrated GPS and navigation… also very futuristic).
