Hi, this is my first post in the forum 
Im considering the return to the mac side
My previous laptop was a Macbook Pro 15 Mid 2009 (C2D 2.53Ghz, Nvidia 9400M), i was very happy except with the graphics in some stuff.
So an opportunity came and i exchanged my mac for a Alienware M15x because since i was very child i wanted a gaming laptop, and like Starcraft 2 was coming in less than a month i didn't thought any more (My dream is accomplished
).
Honestly i miss OSX (that was my first mac, i only stayed with it 4-6 months), and the battery principally, right now im happy but like traveled to Germany the battery in my M15x i perceived it very low (less than 1:30 hours compared to the 5 hours of my MBP).
First i have to sell my alienware, but i don't want a "drop" in performance and go with a MBP 13" with C2D, and also i want to play SC2 in OSX, no bootcamp if is possible, is the only game that i will play apart from WoW and Ragnarok Online (when i was with my old MBP i tried to play the game in OSX, im going to continue trying).
The most possible option for me is the MBP 2010 with Core i5 2.44/2.53, i see those models have a Nvidia 330M (is not too much difference from my current GT 240M), how is the performance in SC2/WoW in OSX? Somebody has problems with that models?
I see that is possible a very close refresh for the 2011 models, somebody knows in which dates is possible to succeed that?
Thanks
