Yup, you can use Photoshop as well, although now that Adobe has gone with their subscription model, it's weird, they've broken up most of their apps into a bunch of free ones, but it's still there and it's so much easier to use with a pen than with a finger.
It's not the greatest experience because of the screen size, but it's not bad.
Sketchbook (if you can draw) is amazing, and so are the note taking features. I keep coming back to the Note line because of the S-Pen.
