recently sold my Mac Pro 1,1 and Macbook Air 11 both for 2200. now im having trouble wondering which one i should buy. i can get the Base Model 27" Inch iMac with 1TB fusion or Retina Macbook Pro 15" with 16GB Ram , 2.3GHz quad-core Intel Core i7, Turbo Boost up to 3.6GHz, 16GB 1600MHz memory, 256GB flash storage, Intel HD Graphics 4000, NVIDIA GeForce GT 650M with 1GB of GDDR5 memory. im confused, portability is not an issue. How many monitors can a Macbook Pro retina hold? also in terms of performance which machine is faster in terms of photoshop, video editing, final cut pro and xcode?
