We'll start with the rMBPs: 1) Good screen resolution, issues with screen quality, uniformity, retention 2) Fast, but not fast enough to be perfectly fluid in User Interface 3) Battery life is in many ways, a downgrade That leads to early adopters that will be satisfied with the current rMBPs, but with clear areas of improvement, the 2nd generation MBPs will spur upgrades.d Planned Obsolescence - 1 year - Apple Success. The "other' MBPs & Airs: Improved speeds and battery life with Ivy Bridge make them even better than last year's but... 1) Still carry outdated screens, Retina screens are inevitable 2) Reliance on integrated graphics - means that next year's Haswell will rocket performance by 250%. Big numbers are what Apple loves to tout in new products. Planned Obsolescence - < 1 year - Apple succeeds again. Looks like 2012 is a transition year.
