Hello All, I am new to the forum. I am looking to buy a Macbook Air. My preference is with the Macbook Air 11" model because I want it to be small. However, I noticed that the 11" models have 2 hours less battery life than the other models. My questions are aimed at those who own any of the current models of Macbook Airs. Is the advertised battery life fairly accurate? Or is it an exageration. Battery life is my second most important factor, and I want to know is there way of increasing the battery life on an 11" Macbook Air to make it the same as the 13" models? I also noticed that the 11" ones don't give you the choice of the more powerful processors. I assume that's because the power supply unit won't be able to handle the processors. Any thoughts or advice on all the above is welcome.
