FWIW (see my post above recommending Air), I also tend to keep 20+ Chrome tabs open at a time, along with Xcode, Photoshop, and occasionally Eclipse. Always snappy. As far as I can tell, it performs better than my previous MBP. It seems like Apple made great strides since the original Air introduction in 2008, turning it from a "toy" expensive computer to a power box for mainstream users and developers alike. This year, I was upgrading from the 2010 Air (2.13Ghz model) to the newer Air (1.8Ghz model) and was concerned that the Ghz mattered here. It appears that the new processor makes a huge difference, since the benchmarks I ran out of curiosity (GeekBench) indicate a 2x improvement, and the actual use ( say, compiling a huge project in Xcode) is significantly faster. Some other benchmarks I read before making my purchase: http://www.anandtech.com/show/4528/the-2011-macbook-air-11-13inch-review http://www.anandtech.com/show/4528/the-2011-macbook-air-11-1... ("Both the 11 and 13-inch MacBook Air are fast enough to replace your 3 year old MacBook Pro and still deliver better performance. You can even move from a 2010 MacBook Pro to an upgraded MacBook Air and not notice any drop in performance. All of this is thanks to Intel's Sandy Bridge CPU.") (I have the highest spec 13" model, with the i7 processor.)
