Nobody Wants Tablet PCs
Maybe Apple is coming out with a tablet PC, but it seems unlikely. It's not a product that makes sense. Tablet computers have been available for Windows a couple of years now; they're not selling like gangbusters and there's no reason to assume that a Mac version will do better, no matter how much magic pixie dust Steve Jobs shovels onto the product.
The rumor that Apple is working on a tablet PC is perennial; it comes up again and again. It came up this week.
Blogger Dr. Macenstein is right: The only times you need a tablet is when you're using a computer while standing up, and that's just not something most people do very often. An iPhone, or some other smartphone, nicely fills our on-the-go computing needs if carrying around a notebook computer is impractical.
