I am fed up of Microsoft since the Win10 update so have decided I'd like to change to Apple (have iPad Air2 but too small for typing). I'm not the least bit techy. Haven't decided between iMac or Macbook Pro. A quick question: Buying today is there still a problem with the retina screens disintegrating? I want something that is super quick - my 5yo Samsung laptop (on it's way out and dreadfully slow) is i5. Is it worth having i7 if I don't do gaming but would like to do more with photography. I'd like at least 8GB and SSD or Apple equivalent (have no idea of difference between fusion and flash). I do a lot of writing and a fair bit of web browsing. Some advice would be great. Thanks in advance.
