I purchased a chromebook, it worked for a few days,then the screen went black with vertical lines.  I called Samsung and they did some troubleshooting over the phone but then said I'd have to send it in for servicing.  I received an e-mail today that they would not honor the warranty because it appeared there was a crack in the screen.  There was not a crack in the screen when I sent it in but now it's their word vs. mine.  They want $169 to fix something I used literally 3 or 4 times.  Don't buy this product or if you do don't expect Samsung to honor the warrenty if it stops working a few days after you get it.
