So I'll be updating this thread but I'm going to be running and posting my 11" 128GB i5 Battery Life results. 3 Hours (Exact) - I had full screen brightness on, full keyboard brightness on, and got through the movies Get Him To The Greek and 1/2 of Waterboy on iTunes in fullscreen mode. I'm impressed with that. I normally only use 1 bar brightness on Keyboard (since that's all I need) and I'm about 50% on screen brightness. I'm sure I'd get 5 hours out of this thing. Going to run some more test with just web browsing too.
