It’s almost embarrassing if I think about the number of PDAs and similar gadgets I’ve owned over the years. And sadly, I’m still looking for the perfect one. My BlackBerry comes close, but still not quite there.
Evan Koblentz has a great article chronicling the evolution and history of PDAs starting with pre-PDA devices and moving to current devices like the Palm Treo. The majority of the article details (with pictures) the earlier late 70’s and early 80’s PDA versions.
