Hello, I currently own a Mid 2009 13" MacBook Pro. I understand that it isn't really that old. It still works fine, however the battery life has become poor with around 950 battery cycles. Here are my options: 1) 13" Retina MBP, Top Model with CPU upgrade, and MAYBE a 512GB SSD. 2) New iMac 21.5", Top model with CPU upgrade, Fusion Drive. As I have mentioned I am currently using a MBP. I do like to ability to move around with it but saying that, I will be keeping it if I get an iMac. I would just like to know your opinions on which is best. Obviously no one owns the new iMac but previous gen. iMac owners, Retina MBP owners. Anyone who has their opinion, please share it. Thank you for reading, I look forward to reading your replies!
