Had really looked forward to this device for my teaching, for one, it should have 'an excellent sound' and using it I just find it OK or passable, and second, the screen has an overall yellowish hue or tint if you want and I find this very very annoying, thirdly the screen brightness  is mediocre, my asus c101 is actually brighter ... I'd wish the reviewers of this device had better and more uniform advice instead of contradicting views... Or, I've been sent it with a defective display, not sure
