My first post here..Just to point out .. Both touch gesture and pen pressure works in 2010 x64 MS Onenote using the same Wacom ISD Driver. There is no reason AR could not adopt the same standard; even though it is not standard with MS. My 2 cents. Though you have a prototype EP121, it should still be functioning as the production units. Just have all you bios, OS and drivers updated. Stock WACOM Pen driver come with EP121 is written by ASUS themselves in script for 32 bit OS and it is not written by Wacom.
