Does the UI do screen rotation cleanly?

Whenever I try that on Ubuntu, with a touchscreen device, it rotates the display ... but does NOT rotate the touchscreen coordinates (so the trouchscreen, and the display, don't agree about what you're clicking on). I'm hoping AI works out the kinks in that (for their version of linux).

Have you had the problem with balance that some people have reported?

What do you mean about having to solder a charger!? Did it not come with one? (or are you saying it only came with a USA charger, and that doesn't help you?)
