I can relate to this because it took a while for me to adjust too. The tactility of traditional media is evidently lost with a tablet. Nevertheless, after much insistence, I'm finding myself using a tablet for much of my work nowadays. Prior to going digital, I used to paint with oils at large sizes (had to stand and climb ladders), thus the nature of my work has changed. This has been enforced by working commercially. In advertising and publishing, a digital mockup is far more practical and accepted. The other principle advantage is that you're not limited by how much detail you can implement, and that the handy Apple+Z (or Ctrl+Z) is a godsend.
I've never been one to conform to rulings, nor was I a particularly good student. I'm something of a free spirit that can interpret what's required of me. At school, I think the general consensus was that I was highly capable, and perhaps even bordering on exceptional in the arts, but an awful student to teach.
