Hello all. I have been a lurker here for years, but just created an account. So how do you justify Retina? Here is my train of thought. You can basically buy a used 13" non-retina current model on ebay for $700-800 in perfect condition (just wait and look and they are there, sometimes less). Slap 16gb of RAM in for $130, and a Samsung 840 PRO 256gb SSD for less than $200 and you have a computer that is comparable to the 13" Retina that costs $800+ less with tax. How do you justify that $800 for a comparable Retina? I have almost purchased the Retina 10 times in the past month of research and the following just keeps stopping me. - I can't upgrade it in the future - If something ever goes wrong with it, I am at the mercy of Apple for even more cost - The Retina display is moot if you want the highest resolution taking advantage of the screen real estate - increased storage speeds that really won't be noticeable in daily operation over a Samsung 840 Pro Where is the value for that extra $800?
