mashoutposse i was not disputing that the more demanding CPU intensive tasks may perform better on the MBA. I do however think that the extra ram may make the system perform faster in some other tasks.
That battery test is interesting. I will read more reviews and see what they say. I have read reviews that have given the MBA just under 3 hours and reviews that have given it 4 hours plus battery life.
This was Lenovos projected battery life. I am always sceptical though of what any manufacturer has to say about projected battery life.

I would like to see future comparisons run the systems as close as possible and that means removing or disabling the dvd drive when testing the battery life. I dont know if C-Net did that as I dont have the time right now to read all the review. Also, I am not sure what configuration of notebook they tested but if you leave the GPS enabled and WWAN on when on battery that will also consume power.
