I have worn out more than one tablet. It is still not the same as using a pencil. I am not sure I could keep a pencil drawing smudge free. I have always had to take a lot of care not to. I am more used to the feel of my tablet than anything else at this point. I use a mouse too. But not for most of work that I do that has fine lines. I still feel pretty rusty. But since you decided to try a few spaceships I decided to stretch myself again too. Thank you for the inspiration.
