I have not bought this Ultrabook here on Amazon, but the dealer around the corner. But I can only recommend this book. Great material, no cheap plastic parts like a Sony Vaio. Great look, the Alu and fiberglass makes the precious book. The screen was compared to a MacBook Air. A bit sharper and clearer than the Apple device. The keyboard is great for writing quickly, the stop is a little loud, but that happens when you write fast. Backlit keyboard is super in the dark and in the bright she is not therefore required off. The JBL speakers that are installed, have a great sound, better than anything I had before. graphics card just top! Image processing so you can too. Now for the battery, the mileage is amazing, I use this device in the university and I can bridge from morning until noon with a charge, is in constant use. Very good.
The service of Samsung's top anyway. Because Sony and Apple should cut a piece.
All in all, you get what you expect for the money.
