Summary: I recently (Dec 2013) purchased a Samsung book 5 NP550p7C 17.3 inch silver laptop directly from Samsung as a back-up PC for work as my old HP desktop was at the end of its life. I chose the Samsung as it was one of the few laptops with a matte screen. I rated it a 2 as it came with windows 8 which makes the entire experience a disappointment, Windows 8 is a poorly designed OS, period. My 2008 Apple Macbook Pro with 4 gig runs circles around the Samsung.
Summary: Wow. It's a finely tuned state of the art PC. I like it even better after wiping Windows 8 off of it and installing Windows 7. Now I have a flash drive with all the Windows 7 drivers for the NP550P7C on it, and my own copy of Windows 7, and I can wipe the whole thing and start over whenever I want. But I gotta say, this machine is fast, pretty and powerful. Gorgeous. I almost bought a Mac, but now that I'm running Windows 7 on this thing I just love it.
Summary: I have had so much fun with my new laptop! Windows 8 required some learning, but the Samsung is swift, has great video, and I love the large screen. I read that it heats up a lot, but I haven't experienced that. I do wish the battery lasted longer though.
Summary: You can't hear the fan running even when it's on full blast. It doesn't get too hot on your lap. It's super fast and the JBL speakers sound great. The only reason this got 4 stars is because Windows 8 is really annoying. It will switch to another screen while you're in the middle of a task with no prompting.
