Be careful, Windoze products still use the registry. They are still OS's that degrade with use and require reformatting every so often to maintain performance.
That leaves us in an unhappy place. I am not only upset about the apple glossy screens, but the newer iMacs are even more difficult to replace HDD's etc.
They have sacrificed service to make it thinner, but thinner makes no difference for me when I am using it and facing it head-on.
A fact of life is that HDDs fail. For a work computer, I demand one that can be up and running in a few hours of a HDD crash. That is simply not compatible with a computer that needs an appoinment and the computer needs to be dropped off. Why? just so it can be made thinner. That is not a good design choice.
I don't know if the new iMacs can have the front screen cover removed, but that is what I have done to my late 2009 27" iMac. The screen is quite fine now. In a few years we should be able to get inexpensive 4k external screens, but that doesn't solve the current problem.
What is the best choice for the pro in the future? it is not so clear. Yes, I feel that Apple doesn't care about us. They make most of their money by selling toys such as iPads and iPhones. I rarely see and iPad being used fo work. As far as iPhones, they are tiny iPods wth terrible phones attached. They are great for internet, but not good as voice telephones.
