I bought a 13inch retina mac book pro a few months ago. I have till next may to add it to and I want to know if you think that it would be worth it to add to one. I had it on my other mac and it defiantly paid for itself but the only problems that I had with it were the HD went out and the opticaldrive went out. My retina has a SSD and I haven't heard people say the go out and I don't have an optical drive. What do you think? Is it worth it to have?
