Hello folks, I am looking at purchasing my first mac sometime this week. After months of research and years of being a dedicated PC user and mac lover, I'm finally making the switch. I am a web developer and my current work machine is dying, so I'm making the switch to mac. I refuse to work on the abomination that is Windows 8... Anyhow I'm looking at two different options on my limited budget - macbook pro non retina, model MD103LL/A or forking out for a retina system. The main thing that is attracting me to the non retina model right now is the that there is an optical drive (sadly I do still use optical drives), the hard drive is bigger, and other than a difference in screen resolution, I'm not seeing any major difference between specs for both machines. If I was investing in a retina machine, I would have to purchase an apple super drive and an external HD, and right now every penny counts. So I was wondering your thoughts. Outside of the SSD and retina display, is there any major difference between the non retina and the pro model I am looking at?
