I agree that there will long remain need for desktop/tower computers for the sheer power, but I don't agree that tablets should be pigeonholed as a "home device".

I've seen plenty of people use them for "light creation" of notes, etc. in meetings, which is a no-brainer.

Beyond that, though, there are LOTS of industries that have been using wearable-type computers for a while, because the form factor is sometimes as important as the power.

Car dealers and medical offices are embracing tablets as lightweight, portable, and perhaps most importantly, easy to learn input devices for their everyday business.

I'd argue that 85% (number pulled out of my rear USB port) of people using computers daily *don't* need anything more than a tablet, or glorified data entry and order-taking/display device.

Tablets hit that sweet spot dead center.
