Messing around and installed Ubuntu on my secondary laptop, GIMP was pissing me off so i went and setup windows 7 in virtualbox so i could still use SAI, and scribbled this up as a test, ended up liking it, and finished it.

and SAI is running good on it too, Always run it in Parallels desktop on my mac, only issue I ever have is some lag with the open or save dialogs the first time I bring it up
