Recently Wacom released an updated version of their graphics driver for penabled Tablet PCs. This release apparently solves the problem of ink lines being jagged, which was caused by the previous version. via [Tabula PC]
Holy palsy, Batman! I thought my digitizer was going!

p dir=ltr> Update: For my Motion Computing M1200, the update works great. It's a little disconcerting -- the first time you run it, it uninstalls your pen driver with no acknowledgement that this is a temporary step. You reboot, run it again, and it installs the new driver. Reboot again, and the tremors are gone!
