I apologize in advance for this topic. I'm a very undecided person. Right now I'm running an Early 2011 MacBook Pro, with a 2.2 GHz i7 processor and Intel HD Graphics 3000 512 MB. I was hoping for an updated iMac 21.5" with this upgrade, since I'm not a fan of the larger screen size for my needs. As soon as it was announced I ordered the new Retina iMac, with the upgraded option for both the GPU and CPU for a total of $3011 since I'm a college student. However, for my editing work that I do, my MBP works just fine and the only problems I've been running into lately have to do with my screen and possibly GPU (had it repaired/replaced by Apple in December.) So I was thinking... maybe I should just hold off and buy a nice 21.5" monitor that I can later use as a secondary screen for an iMac along with a trackpad / keyboard and just use my MBP for now with an external display. That way... whenever they actually do announce a Retina/upgraded 21.5" iMac, I can buy that and even use my monitor as a second screen. So my questions are: 1) Has anyone used their MBP without the display and just permanently hooked it to a monitor? How well does that work? Do you leave it on always? Are you using an Apple Trackpad or another brand? Any questions you could answer would be beyond helpful! 2) Is it really worth putting $3000 into right now if my current computer is doing fine other than occasional display issues and a recently replaced GPU? PS: That was about 1/2 my savings account but I felt it was justified at the time... Again, I'm really sorry about creating this topic, but anyone who could answer a question or both would really help me out. This will be my largest purchase since my MBP although my mom paid for most of that as my high school graduation present.
