I waited and waited and then the update to MBP came. It was all I wanted on paper, thinner, more powerful, with retina display. I spent hours in the Apple store, and still, after all my reasoning couldn't bring myself to buy Retina. So I got i7, 8GB, 512GB SSD. Why? i7 is as fast in the real world terms as the retina i7 although to get retina i7 its 200 more. MacBook Air is still more portable, looks slicker, and has that special appeal that I just don't get with MBP Retina. Using MBA brings somehow more natural usability feeling (could be due to the curve of the keyboard, starts of from almost surface level and it rises), but its different than the one on MBP. MBP Retina has issues - yep... 12 - 15 hours of uptime = all day long. If I need to replace or upgrade something - I can, its not glued to the case (this wasn't really a concern but it kept lingering in the back of my mind). Unless you're looking at the retina screen you won't know you miss it, so at the end of the day are all the trade offs worth the retina screen. I couldn't do it, so I guess not to me.
