The mouse is subpar, but functional, and the keyboard is completely unusable.  Right out of the box half the keys don't even work.  But I wasn't buying for peripherals so I'm gonna let that slide.Biggest thing is it crashes constantly.  I get about 20 minutes of use time with the installation of Windows 10 it comes with, then I get a blue screen of death with a different error message each time.  Sometimes it's MEMORY_MANAGEMENT, sometimes its KERNEL_SECURITY_CHECK_FAILURE...I dual booted Ubuntu to see if that's any better, and so far it seems okay.  It still crashes, but only once every few hours.  So I can at least get SOME work done before it drops out.I was only buying this as a backup while my Macbook gets repaired, so for my purposes I think it's just fine.  But for anyone who is purchasing this as their main PC, I would advise against it.
