Ive noticed so many people seem to think that you can't work with a tablet thats too small. Ive never used anything larger than 4 by 5, it its fine. Im wondering if you guys have your tablets set proportional to the screen? If you do, when you put the stylus in the uppper right corner of the tablet, it goes to the upper right corner on the screen. So really if you wanted detail all you have to do is zoom in.
Sorry if its obvious, but i thought it might help soem people save a couple hundred bucks. :-/
Don't just practice. Also Practice the right things, the right way.
