We've been keeping track of Alienware's M11x series since the very first one landed and have had the privilege of testing each one. The move from Penryn to Arrandale in the R2 netted a substantial boost in performance at the cost of some battery life, though that issue was mitigated somewhat by the introduction of NVIDIA's Optimus graphics switching, replacing the more finicky software-based GPU switching in the first generation model. With the vastly improved power consumption and efficiency of Sandy Bridge, do we have a true successor to the last two models?

In the second half of our Mobile Buyer's Guide, we focus on portable machines with screens smaller than 14". The market as a whole is getting a thorough overhaul over the summer, both because of brand new chips coming from Intel, AMD, ATI, and NVIDIA (for those of you keeping score at home, that's...everyone) and because of the rapidly approaching back-to-school season, which always means newly refreshed notebook lineups. With so many new systems out there, who's going to put in the groundwork to figure out which ones can hold their own in the market and separate the contenders from the also-rans? We did, and our findings are in this article. Read on for more details!

Four months ago, Alienware turned the mobile gaming world on its head by cramming a reasonably fast GPU into a small chassis with an 11.6" display. We loved the concept of an ultraportable gaming laptop, but we had a few complaints. Now Alienware has returned with the updated R2 model, sporting NVIDIA's Optimus Technology and the same GT 335M GPU. Added to that is an Intel Arrandale ULV processor, our first laptop to use such a CPU. That addresses two of the biggest concerns we had with the original, but does it make for a truly better laptop? Today we'll look to answer that question with our in-depth review.

A few weeks ago, Alienware launched a revamped version of the famed M11x, the world's smallest gaming laptop. We've been pestering them to get a review sample ever since the press release, as we know there's a ton of interest in the updated M11x. Much to our surprise, a package arrived unannounced yesterday with said laptop. We quickly unpacked the system and prepped it for testing. We already liked the original concept, and the R2 release improves on several areas. Specifically, the old overclocked CULV SU7300 processor was swapped out for a Core i7-640UM and the GPU now has NVIDIA's Optimus Technology to allow seamless switching between the Intel HD IGP and GT 335M. We'll be running benchmarks over the weekend, but today we wanted to present our initial impressions.
