Ok I am trying to compare the 13" and 15" Macbook pros, wondering which one I should try buying when I get money for school. I am going to school for information technology and need something more mobile, than my 21.5" iMac and I was just wanted to hear some users feedback. First off I know there is no core ix processors in the 13" but kind of like the smaller 13" form factor. Anyway would the 15", be to big haven't got anywhere to go to really look at them, but saw a 13" and that was pretty cool. Also considering there are still people who rave about the older macbook airs is it really such a big deal that there is no core i's yet. Just wondering your thoughts and is 13" big enough to u? I do plan on putting 8gb's and a ssd in whatever I buy. So that should help with more speed. 
Are the core 2 duos that bad?
Is it worth it to buy the core i5 yet?
Your thoughts and any other commits to help me decide would be nice!
