Windows tablet accessories?

Is there someplace where I could purchase accessories for 11.6" windows (or other) tablets? Something that ships worldwide (so amazon is of the list).

Specifically, I am looking for a tablet stand. I plan on purchasing a samsung ativ smart pc 500 but I'm not sure I'll be purchasing a keyboard. So a stand would be a must. I'd like it to be such so that I could use it on uneven surfaces (my stomach).
