This was the worst Chromebook I've ever owned.  In under 6 months, the power adapter died and I had to buy a new one.  It was also around that time that some of the wallpaper graphics started fading out and the performance slowed down.  One of the adapter inputs stopped working as well and keys would get stuck often.  Now, it's been less than a year and a half since I bought it, and the performance has been awful.  I looked up some articles on how to speed things up and removing some of the bloatware did help the speed a bit.  I finally wised up and financed a Macbook, which performs a zillon times better.  I recently tried to go on the Samsung to look up an old bookmark.  It now won't charge or start.  Probably needs a new adapter again, which I'm not buying.  The best Chromebook I ever had was Acer, so I'd recommend doing that if you don't want to buy or finance an Apple product.
