I am definetly going to switch to mac. Windows is getting annoying and too much touch interface in the next OS. But I am stuck at a crossroad between the 13 inch and 15 inch. I am hoping that you guys can help me decide. Some notes: I need to run applications like Adobe CS5.5 (Mainly PS and DW, video editing is the least used) I would very much like to be able to run games like Assassins Creed 2/Brotherhood, Lord of the Rings Conquest, etc. without lag (minimal is fine) I will be bringing it to school occasionally, maybe more later on. (HS) So my main focus points are... Is the 15" portable enough to bring with me to school, or is the 13" a much better option. And will I be annoyed by the lower resoution of the 13" since my current resolution is 1366x768? Finally, will the 13" be powerful enough to do the above things with ease? Price does not bother me much FYI.
