I also use the Surface Pro (original model) for digital painting at the moment. I noticed in your review that you recommended using something else other than the kick-stand to prop the machine up; what do you use?
I've not tried drawing onto the surface whilst it's propped up. At the moment I lay my tablet and type cover out flat on a under-cushioned dinner tray so I can access the keyboard on the same plane as the screen which is handy but its not ideal XD It slides around and the type cover can sometimes move into a position where the surface thinks it's been folded right back (and therefore the usage of the keyboard is locked-out). I could do with some clips to hold it down, or something :/
The idea came from this guy: jonathancase.net/my-transition…
How big PSD that you would like to work on? For me, it performs really well on 4000x6000px with 10-25 layers. (My machine has 4GB of RAM)
did the stylus come with it or did you buy it seperate?
