What's your tab?

I am looking to get a new tablet. Sketching is the only * special* thing I want to do on it, all other functions are normal order. My short list is :
Asus Transformer
Samsung Galaxy 8.9

I guess I should say I want something easy to carry and somewhat light weight. I also am thinking of getting a Nook Tablet to use as an e-reader and for whatever.

What tablets are you all using? How do you like them for sketching, what pens are you using? What don’t you like about your tablets? I am open to other suggestions, if it is Android I’d want it to get an ice cream sandwich update.
