I thought this was worth posting on it's own rather than burying it down in my iPad Alternative thread.
For me, this opens up a lot of options. The Android Market now offers Sketchbook Mobile that was previously only available as an iTunes app.
My question is the android version of sketchbook any good? I played with it shortly on a nook (you can install the full android os on it) and it wasn't quite appealing. Then again I used my finger and it was the free version.
