I've been lucky enough to have ok_ish hardware with nothing broken to the point of not functioning yet, but the firmware is still unstable, buggy, and outdated.
So, join the club. GN 10.1 defintely looks like a go with the side by side multitasking among other things. It should be a worthy replacement though honestly Ive lost enough confidence in android (at least for tablets) that I may wait for Windows 8.
Besides all that, as an artist the pen lag and super buggy version of sketchbook pro are not inspiring confidence. Also the (still!) lack of a pen only mode.
