So I have a SP2 i5/256, if I upgrade to either the i5/256 or i7/256, how good is the new pen input for drawing? I use mostly Photoshop, and SAI. I installed the waycom driver so I can use the pressure in the Photoshop. The only issue I hate is the pen can be almost 1/8th in off in the top left corner so clicking on the small menus can be a pain. Is the new pen any different? Especially since they released the new update for the pen? Can you really tell the difference in pen pressure from 1024 down to 256?
