More Info Samsung Series 9 (NP900X3A) laptop review Samsung unveils redesigned Series 9 laptops with 13- and 15-inch displays, starting at $1,399 Spotted: the elusive 15-inch Samsung Series 9 Before there were Ultrabooks, there was the Samsung Series 9. When it arrived on the scene last year, measuring .64 inches thick, weighing 2.8 pounds and packing a blazing SSD, it seemed to offer Windows users the closest thing to a no-compromise experience -- provided, of course, they were willing to pony up the requisite $1,649. As it turns out, the Series 9 was great -- memorable, even -- but not without flaws. It lacked an SD slot, the trackpad was jumpy and the display resolution topped out at a humdrum 1366 x 768. A year later, Samsung is back with a second-generation laptop that promises to correct all of these shortcomings, and ushers in an even thinner, even lighter design. Make that two laptops: Sammy's selling a 15-inch Ultrabook, too. And truly, there's nothing quite like it: nothing quite this thin, with this large a screen. (Consider for a moment that it measures just .08 inches thicker than the new 13-inch Series 9, which is already thinner than most other Ultrabooks on the market.) As always, though, luxury doesn't come cheap. The 15-inch Series 9 will cost $1,500 when it ships at the end of this month (the 13-inch version is available for an also-pricey $1,400, though we haven't gotten to take that model for a spin yet.) Ultimately, then, are the Series 9's elegant aluminum design and 1600 x 900 matte display enough to justify the premium you'll pay over other Ultrabooks? And does the 15-inch version offer long enough battery life to match its larger size? Let's find out.
