Okay, so I'm not buying yet but I still want to start looking. I'm having such a hard time deciding on what I should get when I finally do get a new MBP. So I'm thinking like this.. 1. I want to be able to get the thunderbolt 27" display and hook it up to the MBP(perhaps even multiple displays?). I saw some posts before pointing out that the 13" HD3000 won't be enough to support the massive resolution of the 27" display - is this true? If it is then I have no choice other than getting the 15" with a discrete graphics card. If it's not true: 2. How portable is the 15"? I'm currently running a 13" MBP and I find it incredably perfect. It's sturdy, not too small but at the same time small enough to be able to bring it with me on lectures. Will I find the 15" clumsy? I guess the best way would be to actually go to an Apple store and check them out to compare but since I'm not buying yet I haven't. I'm lazy 3. Another reason for getting the 15" for the discrete graphics card is for my gaming. I don't play a lot and not really any graphic intense games. Mainly World of Warcraft and Starcraft 2. It would be nice however to be able to max them out. Would it be worth it to get the high-end model with 1GB GPU-memory? 4. If I decide to get a 15", would it be worth it to get the hi-res screen?? I think that's it. Basically I'm wondering if the 15" would be worth it for the performance-boost it gives over the 13". The 13" is after all 1000$ cheaper(and in Sweden the difference converted to dollars would be the equivalent of 1600$).
