Just got my Irex delivered. The first thing I checked for was the stylus. It is included. Second thing, I notice is that the chassis is made of plastic and there is a slide shave where the edge of the back cover connects to the front face. It exposes the inside black color of the plastic. Hence, making it seem like the cover is deformed by a screw driver. However, carefully inspection showed that is not the case but a result of poor manufacture quality.
I have some hand on experience with Sony PRS 900. I have to say that I can see the stark difference in build quality.
I also tried the Wacom Graphire 3 Tablet's stylus during calibration. It's a no go. No respond when I used it to hit the x mark during the calibration.
I'll see whether I can live with that little defect on the chassis.
