Quote from hessibiggest flaw: near the sides of the display then pen flickers all around which is kind of annoying when you have important controls there. depending on your calibration you wont be able to open a hidden start menu (windows) or dock (mac os x).when it comes to the other stuff: the display is okay. it seems to be a little dark, but not too bad. the colors match my macbook pro displays colors really well. the pen works really good. feels as working on an intuos3 with a display
you have a pivot point unter the display which is cool for rotating the display when it is flat on your desk. if you don't like this behavior you can put some rubber stamps underneath it BUT you can do this only once. this is a big fail imo. imo the cable from the converterbox to the actual device is pretty long. if you put it on your desk you will have too much wire on your desk. the pen that comes with the cintiq is basically an intuos3 standard pen. it comes with 3 extra default nibs, 1 spring nib and 1 stroke nib. also there seems to be a really small delay in drawing. usually you dont notice it, but if you wave around a scrollbar in firefox for example after a while you will see that it is delayed. probably i should make a video of that.
overall: the device is cool especially when you dont want to spend 2 grands while still having a cintiq. there are some technical flaws that you an live with or bypass with the calibration. i dont regret buying it since it is damn awesome to directly see what you are painting.
i give it a 4 of 5 points. if there will be an improved second generation you should probably get one of those. at the moment there is nothing confirmed about such a thing.
when was yours manufactured? mine is from feb 08 (says on the bottom i reckon)
