I've bought it 2 weeks ago.
First, I went for the 16GB version.
I had to discover the strangest thing: The SD (SD, not Micro-SD!) only can be used for file transfer, but not for App2SD!
Then of course 16GB are way too limited. Even 32GB (the maximum, Sony offers for now) is somewhat critical. No biggy for me, it's only intended to be an additional/specialised tablet. Still, I exchanged the 16GB for the 32GB model without problems (had to pay the difference of € 120 of course).

Originally, I had decided against Sony Tablet S about 5 months ago. The display seemed too dim and it's all "plasticky".
Then I bought Sony Tablet P and absolutely love it. The "true black" of the display for example. So eventually I re-considered and went for Sony Tablet S.

I find the form factor very clever. Because of the "bulk" (one side is way thicker than the other. Sony compares it to a magazine folded back), it really rests perfectly in your hand (if you use it in portrait, in landscape I find it kind of awkward). Wheres iPad for example, with it's '**=?=(&& curved edges (I liked iPad 1 way better than iPad 2 or 3 design-wise) after some time (> 2 hours or so) simply gets uncomfortable to hold.
And because of the "all plasticky" Sony Tablet S is really light.
So I decided to make it my tablet for reading. So far, I had used my phantastic BlackBerry PlayBook for that. Only downside with this: I only have Kobo and Kindle cloud reader on PlayBook.
On Sony Tablet S, so far I have:
Kobo
Nook
Kindle
PagePlace
Textunes
Txtr
Pubbles
Zinio

As for the "dim display": As with many tablets, the automatic brightness is tuned down, probably to conserve battery.
In the "right" environment or without using the auto brightness, it's as great as Tablet P: "True Black".

Nice add-on:
As Sony Tablet P and Xperia PLAY, Sony Tablet S also is "Playstation certified".
Rumor has it, this even will mean PSP titles later on. So far, it's Playstation One titles.
The ones in the official Sony store aren't very interesting.
But you easily can use the great Playstation emulator from Sony with your own games. I've done so with R-Type and Parodius. Perfectly emulated.
And you easily can use the WII-remote, instead of the '&/E§$&/(/&%/ onscreen controls.
On Sony Tablet S (not on Sony Tablet P, though) you even can use the original PS3 controller.

That's what I love about Android: You don't need to jailbreak respectively root, you can install tons of tools like using your WII-remote, directly from the original Android market (now Google Play).
