My wife is the original owner and the Bolt has performed brilliantly for about a year and half. In September she dropped the Bolt on the ground and the top 2/3 of the screen now has a dark shadow over it. Please look closely at the second photo.
Everything else on the Bolts works fine: all buttons, all screens, the wifi, the bluetooth, everything. My wife has been using the computer for the last 2 months and it's been fine. The screen also functions (and the backlight works) and in good light (or with the backlight on) you can read the top 2/3 of the screen. But in dim/dark/shaded conditions the top 2/3 of the screen can be tough to read.
