My 4 year old 15" MBP has been freezing a lot and stuttering way too much on even iPhoto (I quit using Aperture because of the performance). I knew it was time to get a new laptop, and having experienced the glory that is the Retina display in my 3rd gen iPad, I wanted nothing more than a retina MBP. When the 15" rMBP came out, I was so excited and really wanted one. But I thought that maybe because this screen is so awesome, I could get the 13" (when it came out) and have a much more portable laptop with an awesome screen. Then they announced the 13" rMBP... I knew that was it. I was disappointed by the specs but I knew I had to have it. I went to the apple store and compared the 13" and 15". I kept thinking about it. With my student discount, it was going to be a $100 difference between the 13" 256gb and 15" 256gb (which btw is also quad core, discrete graphics, ect.). So I decided to get the 15". I told the guy that was helping me and he sent some sort of signal from his iPad for the sales guy to come help me check out. The sales guy came out and asked me what I was using it for, I told him (web, email, light photo editing). He told me that I wouldn't be using the processing power and that I should just get an air. I tried explaining to him the awesomeness I felt from the iPad's retina display (I have owned the 1st, 2nd, and 3rd gen) but he wouldn't budge. I got pissed off and told him fine let me thing about it. I realized that I wanted something more portable. The 15" was just way too big. I don't care how light it is, I don't care how thin it is, it takes up a lot of space. So I decided on the 13". Then I looked at the specs and realized that I would be spending $450 more just for the retina display. So I decided to go with the air. I have had this air for almost a week now and boy am I happy! This thing is awesome! I still get goosebumps every time I see it sitting on my table because of how sleek and thin it is. Even though I got the barebones base model 13" (I plan on upgrading next year cause I hate buying mid-cycle) I think it is performing brilliantly. I couldn't be happier. I just thought I would share my experience just incase anyone was going through the same thing. The bottom line is this: Sure I wish this had a retina display, but having a laptop this thin and fast with a retina display is probably at least 3 years away. Might as well get this screen with all of the other benefits (which I believe make up for the resolution).
