Ok guys, I sold my netbook today and I'm going to replace it with a 13" MBP or a MBA. I have a 17" UMBP that I use as my primary machine. The reason I want a small Macbook is to carry around and to take to class. The small MB will be used almost entirely for browsing the web, and editing word docs. I may put some music on it, but my 17" is the workhorse and it'll hold all of my media. The 17" is awesome at home, but I don't like carrying it around. It's too heavy, and I really don't want to ding it or leave it in a classroom unattended during breaks. I won't be playing any games, editing pictures, or anything else requiring real horsepower. In fact, the Atom based netbook was perfect for my uses except for that fact it was XP and not OSX and I really just can't stand Windows anymore. I want it out of my life. My wife has the 13" UBMB in my sig, so I'm very familiar with that chassis. What do ya'll recommend?
