Today, I originally planned to buy a MacBook Air 1.86 GHZ Rev C. I really thought I had my mind set on the computer. I tried justifying reasons why I needed something that portable. I also tried justifying a performance loss with more expense attached. I have a 2006 Mac Pro at home, so it wouldn't have been my main machine. I previously had a PowerBook 12" that I purchased 4 years ago for $1700. I sold it after 3 years, and I decided to wait till the time was right to buy another laptop. I wanted the Air badly when it first came out, but it was way to expensive. Today was the closest I've ever been to buying one, but I just did not see a future in the system. I knew I could live with the specs today, but I didn't feel like 2GB of RAM would be enough in the future. It seemed as if the Air would not last as long as the PowerBook did. I really liked the fact that I could buy the 2.26 GHZ MBP 13" and upgrade the RAM and HD later if I needed to. If I could have done that easily on the MB Air, I probably would have gotten it. I also liked the MBP's longer battery life and cooler operating temperatures. So far I haven't had any problems performance wise with the MBP. The portability is also really good. It is obviously a little bit heavier than the Air, but not enough for me to really care. I don't notice the thickness at all because the build quality is so good; it is definitely the sturdiest portable I have ever owned. I see people rushing around to meetings with their laptops in their hands at work, and I feel like they would be better off with Airs. I need portability, but I know that I will not need to move the computer more than a few times a day. Everyone has different needs, and I thought that the MBP 13" would not meet mine, but I have been pleasantly surprised. I was prepared to pay the 10% restocking fee if I needed to return it for the Air, but I don't think that will be happening. I will give it a week just in case to see how it goes, but I think I might have made the right decision and saved $300 in the process.
