I think at the dawn of PCs there was a company with a name like The People's Computer Company. If not, it could have been the name of the whole industry.
This is what all the heroes of the 80s were thinking at the beginning. We're building tools to give power to the people.
It was an extension of the culture we grew up in, the 60s and 70s. Power to the People was a big idea then. I think it's going to be a big one again, in reaction to what the computer industry of the generation after the hippies is doing. Zuck is going to create rebellion. Apple and Larry and Sergei too.
The first product of the PPC will be a PC (of course) with all its ports open. With disk drives and an Ethernet jack. Slots. Nothing new. But the things that are disappearing from the "Post-PC" computers everyone is talking about will still be there on the Post-Post-PC.
I don't mind carrying around something a little more clunky if it can be connected to something we haven't dreamt up yet.
