The battery runs dry rather quickly.
On Samsung Galaxy Tab 8.9", in the task list, I easily can switch off all notifications (one of the main battery hogs). I can't do that on Sony Tablet P or the other tablets that conveniently.
I have to track the battery consumption on Sony Tablet P. But so far, I'd say it gets maybe 5 hours. It certainly seems way less than on the "benchmark" tablets such as iPad 2 or Motorola Xoom.

For some apps, the gap between the 2 screens turns out to be more distracting then I would have expected.
I've just tried to play Sudoku. It's no biggy, but to me it's kind of annoying that the cells of the numbers appear bigger in the middle. (Of course they aren't really bigger, it just appears that way as they're stretched because of the gap). So I've installed and de-installed quite a few apps, because I simply don't like them on Sony Tablet P. I'll use those apps on another tablet.

And what I really don't like, although it's not Sony's "fault": Some apps don't rotate, but are designed solely for portrait orientation. I want to hold the Sony Tablet in landscape format (the 2 screens above each other), but some apps simply don't allow for that.
