I suspect some of the "256/512 isn't workable" is sometimes numbers snobbery rather than experience, but I accept some artists with a sensitive touch might find this limiting.
Asus doesn't list the levels on their official site, but for my purposes it compares quite well in use with a Wacom Bamboo tablet with 1024 levels of pressure. There are various reviews and comments that the EP121 has only 256 or 512 levels of pressure (you'll also very rarely see 128 or 1024). I believe newer tablets like the Surface Pro 2 use Feel drivers, available from: Since Wacom recently introduced new Feel technology, those older Tablet PC drivers can now be found at:, under the tablet model select Tablet PC. I may have downloaded the Tablet PC drivers from Wacom's site. I can't remember exactly what I did when I updated to Windows 8. The EP121 screen comes with a Wacom digitizer built-in (as well as touch), so it's using Wacom TabletPC drivers (sometimes known as Penabled technology).Īsus's support page had the drivers for Windows 7, 32-bit: Under the Touchpad category, Wacon ISD_DualTouch (yeah, Wacon with an N - typo on the download page):
Windows tablet/slate PCs with pen technology tend to be either Wacom or N-trig (although I believe there are a few rare exceptions).
