So much so, that last night, when I was sketching in my pad, if I made a mistake I kept on wanting to press Ctrl Z instead of using my annoying smudgy rubber.
And my left hand actually kept twitching, it's such an automatic thing for me.
Maybe this is a sign I should invest in an iPad type thing for my sketching. Though from what I can make out, they aren't pressure sensitive yet, so you can't get variation of line, so I don't think it would do the job for me sketching-wise.
Maybe on the third or fourth generation I'll find they'll do the job.
Anyway, here is one of the sketches I did.
I've called it, "Supermarket", "Toyshop"
