If I truly want a high end pressure sensitive tablet or tablet PC as an artist I'm going to look at a Wacom Companion for the same price as a loaded Surface.
i am impressed wacom launched the companion(s) with so few issues. I think the size, pen and function buttons push it over the sp3 as a pure art play. I almost bought one when they dropped the price $200 in February. A slimmed down companion 2 could be compelling.
