Often won't boot, when it does it takes up to 30 minutes.  Poderously slow and freezes loading web pages, frequently crashes with blue screen.  Did this almost from the start, should have returned it, but it just got slower and worse till past the warranty.  It's been 6 months and I've gone back to my old Windows 7 machine which at least runs.  Sorry to leave a bad review but no excuse for this bad this soon.
