mid '10 15" MBP . . . my display acts up once in while, especially when hot, so I think the GPU is having issues. I have a really old '09 Mac Pro too. Thinking I will do like most people is just have a laptop henceforth. Both have lasted much longer than planned so I do have the money set aside. I was waiting for the MBP to go back to the old reliable keyboard is now it's here. Also glad that Apple essential has the Magic Keyboard that I'm using with the Mac Pro on the new 16".OP:
What do you have now?
Is what you have working well enough, at least for now?
If so, there's no rush to upgrade... yet.
But if you have money that's burnin' a hole in your pocket...
... the "base model" MBP 16" may be just what you're looking for!
