I've ordered the rMBP based model but am no questioning my decision based on performance from a Best Buy display model. Side-by-side ___________ New MBA 13" base model ran perfect, web pages were quick. New rMBP base model ran native applications OK (not great, just OK) but web browsing was HORRIBLE. Even bumping the resolution to the lowest I still noticed slight hitching/fps drop. On the recommended setting it was like a mid grade laptop from 4+ years ago depending on the website. To be honest, I was swooning over the specs and preordered but feel somewhat relieved that they are delaying orders now. The specs are much better on the PRO but due to the Retina display or whatever other reasons it performs worse than any other Mac laptop currently available for the highest price. What am I missing here? What should I get at this point? I was looking for something powerful yet very light due to the fact I would be taking to and from work daily (mostly office products, some very light adobe work and remote access). At home, I wanted to play games such as Diablo 3, Skyrim and the COD series on mid-max settings. Lastly I would use this as backup for most vacation media. The only thing selling me with this over the MBA was the dedicated nVidia chip, which seems to be mostly useless as it is working overtime to render the additional pixels.
