many hand(held)s help more than one

The world of PDA, like the era of home computers, was rich in diversity. There were countless operating systems of which EPOC, Palm OS and Windows CE won out in the end. But Newton OS has a special place, at least in my heart, because the MessagePad was such a terrific device.

It will take me some time to add all the information for each device. Still under construction!
