After going through 2 faulty hp laptops in a month, I decided to try Lenovo.  We have Lenovo pcs at work and they are made well and are very reliable.  Setup was pretty easy, haven't upgraded to windows 10 yet.  Dolby sound is excellent  (better with headphones).  It does have a lot of bloatware as other reviews have mentioned, it took me 30 minutes to uninstall and I definitely noticed a performance increase.Edit 10/30/15I am sending this unit back. The keyboard is awful it doesn't register some keys that are pressed.  The keyboard isn't solid and dips in the center when typing. I've learned my lesson buying laptops under $500.
