JUST switched to tablet after 2 years of mouse (had big tax return check so i was like fuck it)
Main differences:
1. Spinning is 10000000000000000x easier. I spin like a god instantly, tho I wasn't bad with a mouse, you just have way more control with tab.
2. It's more fun, hovering the pen above the little pad is fun I don't know why
3. Hitting small notes is easier.
4. Streaming was easier with the mouse, tho im sure that will change.
The same day I bought it I improved a few of my SS's, in a couple weeks im sure the improvement will be drastic if I keep practicing.
