Firstly, you cannot use the stylus for general interaction on the flyer. Only for stylus-specific notes and drawing.
The tools are very limited. Only a few apps use the stylus. there are only a few brush types, and the worst part, is only 8 colors, plus B/W. Not useful for color work. But for B/W, sketches, it's fine.
The good points are, the pressure does work. about 256 levels like an old-school wacom. The pressure curve is a bit odd... as you have to push harder than I would like for full pressure, and it seems to not go quite as light as I'd like, but it is totally useful, and accurate.
No Tilt.
Eraser is triggered by holding a button. It isn't a soft eraser, very hard edged, but fine.
Pen on Glass is a bit annoying. I fixed that by getting a matte screen protector. It has a bit of tooth to the surface, so it feels much better. More like paper. It does dull the screen contrast and clarity a bit, so you take a bit, you give a bit. cestLaVie.
I love the form factor of the tablet for general use, but to draw on, it seems just a touch too small. That said, I do draw on it, and it's not bad. Just wish for a little more room sometimes.
In the end, it is the only ultra-portable drawing tool, and it does a good job but not a great one. They could use a lot of tweaks, and hopefully they'll get there. At least they used artrage as inspiration for the brush UI.
