I had (well, still have, but don't use) a w510. It worked just as well as the t61 before it (which was to say, they both did great under Linux), but it didn't have hybrid graphics... it was Nvidia all the time. The only reason I've replaced it was that it had absolutely abysmal battery life. Old job bought me a comparable ultrabook that weighs 20 pounds less and has 3x the battery life and I couldn't be happier.
