Smartphones and tablets are at least 15 years old too. Bill Gates used to run around CES telling everyone that tablets were the future. Anyway, for the "Post PC era" to truly take off, we're going to need portable wireless keyboards that "just work". Tablets are going to replace desktops for most people, once we figure out how to attach better input devices. The Microsoft keyboard does appear to be a big step in the…
Does "post PC era" even have a meaning to anyone other than tech pundits? Is tablet hardware really better, or do people just prefer the software experience? In a world of commodity hardware that distinction is quite important. People will buy an IPad because it is easy to use and will reject the Windows 8 laptop because it is hard to use and ignore the practicality of the hardware.
Meanwhile for $500, you can get a cheap plastic laptop that will break on its own through normal wear and tear. It runs an OS that is far more advanced than what you need. The OS needs maintenance, and you need to pay attention to what you're doing. It's super hard to keep a computer running. You might not think it is, but look at the existence of Geek Squad and how many people are afraid of their computer, or can't do simple things. But they're using iPads like an expert.
That's post-PC. You and I will keep our x86 systems with massive globs of RAM and terrabytes of hard drive space because we need them. And the rest of the world will finally get to use their computing devices the way they want to use them for a change.
