It's an interesting time. At the rate of mobile chip development current processors will be severely obsoleted in a year. Early joiners (like myself), are guaranteed to get stung as the future holds devices that aren't just incrementally faster, but offer computational capabilities that these tablet's cannot match.

For example, running desktop software on the Tab would be frustrating at best. Beyond simple tasks, the Hummingbirds just can't keep up with the demands of desktop software, and the RAM limit is severely restricting. I notice this with my Atom netbook which is quite a good deal faster than the Tab.

But that's not to say that the Tab isn't fast enough, I believe it is. Optimization seems only to be a thing worth doing in performance constrained environments (ala the Tab, or for game development), and desktop software is needlessly bloated and slow.

In any event, in around 1 year from now, mobile SoCs will match Atom in speed without the same power requirements, and the world of desktop software will open up to mobile devices.

Mark Shuttleworth of Ubuntu fame, seems to be banking on this, and is readying Ubuntu for touch-friendliness, as well as investing resources into Android/MeeGo/Ubuntu crossovers.
