I'm using the Adonit Jot Pro at the moment. I plan on using my iPad for art purposes and got the Jot Pro enabled ProCreation app.
My only concern is how thin the tip is, I'm a careful person but you never know. I can't stand the floppy black tipped ones, they're just so ICKY.
I'm always keeping my eye open for something else though, have a feeling I'll be using the Jot for awhile.
