People have complained that the screen hurt. I've read it can get hot when you're pushing it real hard, but it gets hot enough for people to complain about the heat, even when using pretty simple apps. Someone was drawing on a cool little app that makes a mirror image of what you're doing, to make a cool looking effect, and said that their forearm was hot. I really didn't think simple apps like that would push the device hard enough to get that hot, especially in an air-conditioned room. If it has a tablet function, I'd expct to be able to pull it off the base without it hurting my hands holding it. When it gets its hottest, I'd probably break the screen if I sprayed it with a screen cleaner. The one that I got is the 128GB i5 version (and yes, I have it updated to the latest version of Windows). It can easily get over 70C, I'm assuming that value in Speedfan is the CPU heat. The glass gets hottest on the lower left quadrant, just left of the middle of the screen, around the bottom of the screen. Does device seem defective, getting that hot? I really like the tablet, and will happily exchange it, but if the heat is "just how the device is", I'll save the money and wait til they make a revision.
