Add me to the 11" love-in, these are fine machines, and it will be my primary computer. I would ideally loved to have seen 32nm Sandy Bridge, USB 3.0 and integrated 3G/Lte in a product this mobile but I digress. I'm seriously considering the 1.6GHz and my question is how much worse is the battery going to be than the 1.4GHz version? And what factors might play a part, eg will they both idle at their max speeds? Etc Very impressed by reports of the 5-hour (and beyond, someone got over 6 hours browsing at 40% brightness!) battery. However I haven't seen any reviews/tests on the 1.6GHz battery yet.
