I've had my pro for five years now and it's now needing too many repairs to be worth hanging onto and paying repair costs. I can no longer even connect to the internet, so I urgently need a new computer. I predominantly use my pro for photography, general use and some games - nothing too complicated. Should I just buy what's on the market now or wait until the end of the year? I want a 13" Retina pro, is the i7 update worth it and will 512GB flash storage be enough? And is the option for 2.6GHZ worth it compared to 2.5? Thank you for your help.
