Hi,
i for one would not like to be without a tablet,definitely.It's great for painting
and sculpting and i got used to it within a few days.
As for the input settings i'm not sure what exactly you are refering to,but in
general the only problem i had were the pen tablet settings of the OS (vista
in my case), had to switch off some.
You can find some useful information on conceptart,they have a wacom related
subforum there.
Hth,J.
