Very good computer but the cooling fan is on all the time and the fan vents are on the bottom. In order to let the fan vent, the bottom of the screen panel protrudes downward when open, creating a long, thin foot at the bottom of the back of the computer, to hold the back of the computer up above a tabletop and let the fan vent. It could not vent if the bottom of the computer were flat against a tabletop, given the decision to put the vents on the bottom.If you use this on your lap, this foot digs into your flesh on top of your legs in a painful way. You have to put some sort of cushion under it, which then blocks the fan vents.Major ergonomic failure on an otherwise very good computer. If you never put a laptop on your lap, then buy it. But it is called a "laptop" for a reason and it fails in that big way. (You can comfortably use it in "stand" mode on your lap, but they you must rely on the touchscreen and have no access to the keyboard.)
