> [...] products that ultimately turned out to be dead ends, like the Palm Pilot [...] Huh? I never had a Pilot, but from everything I've read about it (and how people who did have one describe it) it was quite amazing, and arguably the predecessor of the smartphone, no? I get that the product line is dead, but the concept was very much viable...
I had several Palm devices. As I recall there was a fairly long gap between the death of PDAs and the birth of smartphones. I certainly did not replace my Palm with a smartphone; I replaced it with nothing, and then years later I got a smartphone. Most of the things that are amazing about smartphones were not present on my Palm IIIe, FWIW.
Anyway, I don't think the Palm Pilot was a dead end. It's hard to see it not influencing Blackberries and smartphones.
