Hi! I'm really interested in buying one of these tablets and would love to hear from anyone that owns one or has used one and what their opinion is. I have a Wacom Graphire and don't like that detached feeling....painting directly on the screen sounds perfect! Any suggestions or opinions on the Cintiq 17SX or the new 21UX? Think it's worth the high price tag? Anything you find annoying about it or glitches? What you like about it? Thanks!! Barbara
