Hello macrumors! First post here. I'm returning my 2010 refreshed mbp 13" due to 'defective manufacturing'. It came with some scratches that came in a form of a clamp being pressed down on my mac. Now I have the choice of exchanging for another 13" or pulling the trigger on a 15". 13" I love the size, compactness, portability of the 13". It seems to be the ideal size laptop for me. I take it to work, I cuddle with it, I play rough with it, throw it in my bag. My wish is my mbp's command. I dont give it a second thought when I want to take it to a coffee shop to finish up some work. On the other hand, it's a bit slower than I expected/wanted. I'm a light/casual gamer, playing mostly SC2. Even on low settings I get some lag in huge battles. I also use this mac for work related things and run VMware. It isn't exactly 'smooth' and tends to freeze or get choppy (this is where i expose out and play with on osx and go back to vmware after 10 seconds or so). Although I can honestly say im using vmware 20% of the time and gaming 10% of the time, it does bother me a bit. Now, will these problems go away with the 15"? I played on my co workers macbook, and even though its 1lb heavier, it feels like more than that.Im trying to justify the exchange of portability for power. I cant really imagine laying in bed with a 15" on top of my lap typing this, and would probably think twice before I want to finish up work at a coffee shop. If apple was able to put everything from the 15" i5 base model into the 13", I'd purchase it in a heartbeat. But this is not the case, and I can't predict the future. So for now I have to decide between them. I also assume the 15" will last much longer than the 13" based just on hardware configurations. Has anyone had a similar situation and can tell me what they went for? Or can anyone offer some good logic so I can stop having sleepless nights over thinking about this? How about other solutions such as pop in a SSD, stop running VMware and use bootcamp, and deal with the lag on sc2? Thanks!
