For me the TF810 is a great device but in hindsight I think the same form factor( with a digitizer of course) in a 10.1" 16:10 screen would be great. I found the EP121 12" screen too long to hold in tablet mode and I still find the 11.6" 16:9 Tf 810 a bit odd to use in tablet mode. A bit too long and too narrow in portrait mode. I find myself going back to use my ipad to read my ebooks. My point is a 10.1" 16:10 bay trail Vivotab Tf810 will be the sweetest device.
