1. I'm with you here. I'd like to be able to just copy files directly on/off

2. Also left handed. I just turn off the menu when I'm drawing/writing, so the close button and everything else is fine until I need it. However, what annoys me is that the pen's mark on the screen is about 0.2mm off from the tip of the contract point, to account for the angle of the pen and the thickness of the screen glass. While it's a subtle problem, it is noticeable.

3. I don't think this is a cost issue, it's battery life. I'm happy with their choice, and you certainly can't please everybody
