My client has a MacBook Pro Laptop, mid 2011 i7 model. Has a 500GB Samsung EVO SSD, and 8 gigs of RAM. She bought a new MacBook Air 13.3", i7 Haswell chip, 500GB SSD, 8 gigs of RAM. She asked me if it was a good purchase. I tested (not knowing Macs well, basic stuff) her older MacBook Pro and it is lightning fast. so is the new MacBook Air, the difference being the MacBook Pro has better graphics card, bigger screen (not the retina model) and a built in DVD drive. And the older MacBook Pro is 3 lbs heavier than the Air. Ah...the thing she wanted the most was the longer battery life on the Air versus the older MacBook Pro. About two hours on the Window side, 3.5 on the Mac side.
Question: Is there benchmark software that you use to verify the speed of the Macs? The difference I see on the surface is the battery life is longer in Windows via Bootcamp. Windows 8.1 definitely uses more battery than OSX Mavericks. The MacBook Air has a higher resolution when using an external monitor.
