hey guys how about a little help?

well i'm hoping for some help from you guys. but before we get to that let me back it up and bit so you guys can understand.  i wanted to get an ipad so i can draw and paint on the go. and after i saw this thing that jim lee did on his ipad i knew i had to get something to start working while i'm out and about with

here is the article i saw with jim lees tweets

i know it says its a "tutorial" but its not.

but i don;t want to pay 600+ for something i'm not going to fully use and not completely to spec for what i'd want.  so i started looking at chinese ipad knock offs. and the cheapest one that would work was 410 bucks and it ran windows 7or it was really cheap and ran an older version of google android. not bad but i might as well get a asus t91 touchscreen netbook.  so now here we are. i'm hoping to find something with a pressure sensitive screen that i can take around and draw/paint with.  cheaper the better tbh. i'm willing to let go of some spec that i'm looking if the price is right.  so do you guys know of anything that fits the bill for me? i've been looking for weeks now with no real results. and the asus t91 seems to be the best option. but i'm not really into netbooks so ...yea. let me know guys thanks in advance
