Now that I don't have photoshop available, I'm sketching more with pencil and paper. This is good, in that I have discovered I'm pretty much as good at pencil and paper as I am at sketching with the tablet. I don't even try to do ctrl+z much anymore (reaching for the eraser instead).
On the other hand, I suck just as badly in traditional media.
Also, the pencil drawings get smeared as the pages in the sketch book rub together, and, without photoshop to clean things up, the scans look pretty bad, too. Sorry.
