I've had mine for a few months now and everything works fine if you don't count all the little quirks inherent in Windows 10, like starting itself back up after you've shut it down (make sure you turn off your power strip or unplug the unit to thwart this behavior, or tinker with the power settings). And the annoying "Cortana." And the fact that Windows Edge is always running in the background even though you're using Firefox as your browser. Annoying, yes, but not insurmountable.So here's the big BUT: Windows 10 Version 1803 (the OS installed in this machine) is set to lose its support in November, 2019. Which means you must update to Windows 10 version 1903 if you don't want an unsupported and vulnerable machine. BUT my machine refuses to update. It goes through all the motions (downloading 1903, installing 1903) then fails. I "troubleshooted" Windows Update. It found 3 errors. It fixed those errors. I attempted to update to 1903 again, and again a failure. Type "winver" in the search window and guess what? I'm still on 1803. The same thing happened on an old Dell of mine. It simply refused to update to the new and supported OS.This is not unique behavior, as many Windows customers have reported similar failures with the current Windows 10 May 2019 Update (1903). So buy this product if you want a decent used machine, keeping in mind that you may not be able to update the OS when it becomes unsupported in less than two months. Caveat emptor.
