the low end 13 inch pro and the macbook are somewhat similar and probably near in capability, except that the new 13 inch unibody pro is lighter, backlit keyboards, an sd slot, slight faster processor speed, and faster ram (DD3 @ 2GB is faster than DD2 @ 2GB).
You'll probably only notice a difference once you get to at least the high end 13 inch or 15 inch macbook pro which starts to have a better graphics card and better processer. everything before that is the same. higher end macbook pros the 15 inch on have 2 graphics cards.
from 2GB to 4GB of ram...sure you will notice a different when you start running a lot of programs. dd3 is faster than dd2...but i dont know how specific because I havent check the latency for those.
Just buy basic set up and install ram yourself. they have tons of text and video how tos by google searching or looking on youtube. you'll save money that way and its really easy.
Ahh ok. Thanks for that link! I compared the 4GB 13'' to the 15'', and it seems like the only difference is paying $200 for 2 more inches o_0
Thanks so much for your help!
