i thing the problem that I have with Apple in general is that I have the feeling that I will spend 2.000 and 1 one year after the definitive version will come, and then I will regret.
Then after the year, you realize that it did not happen, but you know that some day it will! and then you know that day is even closer, since you already waited 1 year.
So, now I cannot wait more, and I will buy either an iMac or MacPro. But I have the feeling that a big iMac release will be then in 2013, with the retina. All of us knows that will come, the question is when.
What a mess.
