I find that the n-trig screen is better then the wacom on the SP1 and Sp2 which makes me wonder where they went wrong. I have my Wacom Intuos and it works great. The corners of the SP2 isn't as accurate. It's enough for day to day task but I can only imagine that editing is tougher. Also I do like having the batteryless design of the SP2 and Sp1 stylus. With the SP3, aaaa batteries are much harder to find. I will most likely pick some batteries up for it so if I do run out, I have some.
