Bought a bluetooth keyboard, stand and case from various vendors, so I can state the following:

Keyboards work as well as expected, but only as the apps allow. So, standard shortcuts for cut/copy/paste/forward word, backward word, etc may be supported by certain apps and not others, or may use different keyboard shortcuts. Not standard, but you get used to it.

There's a little stand, keyboard and kit available from Amazon - colid=2P4XUN7CBV7US&coliid=I196F0EOVI127S

Keyboard is plastic-y and cheap but works (note it's the Apple layout, so very annoying), the little portable stand is superb. The rest of the kit is fluff. So why was I interested in this, when the keyboard's a bit naff and the stand is pointless if you have a good case?

Because most of the cases for GT2 are big clunky things that wrap around the device and add weight and bulk (e.g. this from amazon). One of the things that attracted me to the device was the fact that it was thin. So I plumped for a thin case with a barely-useable stand feature (the front cover folds into a little triangle) from ebay at this link.

Note that Amazon are now selling the Tinsky cases again, which seem altogether a better bet than the one I got. (see here for details).

Most cases just stand the device in landscape.

Steer clear of cases that have "slides" to hold the device in place - very poor - the device slides out if you carry it "upside down". See here for an example.

That's it - hope this helps.
