The power button is right where the delete key would be on a Windows keyboard, which means my muscle memory makes me hit it over and over while trying to write normally. Fortunately, it always asks if I'm sure before it actually tries to power down, but it does disrupt my workflow.The right-click seems to be completely non-functional on this model, so anything I need a right-click to accomplish (like pinning apps to my quick-start bar) I just can't do.When I went to write this review, one of the features I was asked to review was the touch-screen; as far as I can tell, this model does not have a touch-screen, or if it does, mine was broken new out of the box.The screen is low quality but serviceable. The sound quality is clear, but the volume won't go very high. The battery life is great. Excellent for the price, a good mini laptop for travel or just carrying around, but not a primary computer for anybody who does a lot of computer-centered work or play.
