I'm currently looking for a replacement for my 13" early mbp that I sold last week on ebay. So I decided to try out a few replacements for my mbp before I added it ebay about over a week ago. I went through 4 defective MacBooks. Below is a list of the macs that I went through. I went through 2 refurbished macbooks and 2 new macbooks during late January to middle of February. 1. Refurbished 13" MBA i7/8/256 - extremely loud fan noise that ran continuously, backlit keyboard too dim at brightest setting. 2. Refurbished 13" rMBP i5/8/256 - ir within the first 10 minutes of use, laggy UI performance. 3. 13" MBA i5/8/256 - yellow tinted screen, washed out colors. 4. 13" rMBP i5 2.6/8/256 - ir after a week of use, the keyboard shocked me when I typed due do the rmbp improperly electrical work, and laggy UI. Yesterday evening, I decided to buy the base 15" non-retina mbp at Best Buy because I really have no use for the retina display, I do not want deal with any ir issues, I want to be able to upgrade the laptop, and of course I still have use for the optical disc drive. I really hope that the base 15" mbp works out for me. I will interested again in the rmbp when Apple implements a white wash that scrolls across the screen like plasma tvs have to wipe off ir, and have a option of self-install upgrades.
