Having trouble deciding between the two. I love to use photoshop cs5 a lot, and may occasionally do some video editing, and want to be able to run both windows and mac on the computer. Macbook air and the 15 inch mbp both have same resolution 1400x900... but the space on the mbp is a lot larger. Macbook air is nice and light, whereas the 15 inchers seem to be heavy.. Performancewise it LOOKS like photoshop runs only very slightly better on MBP15'' compared to MBA based on youtube videos, CORRECT ME IF IM WRONG. I currently have a 11'' macbook air with my windows laptop 15.4''. My original idea was to just have mba as the portable laptop (can remote into the 15.4'' when necessary on travel), but now that my 15.4'' laptop died (was a 2.4 ghz core 2 duo)..... I am struggling to decide whether to go with the 15.4'' mbp or just get a 13'' mba.. though it may be strage having two mba. any thoughts?
