15" retina display, i7', 16GB RAM, SSD, alloy case model. This was a $4k purchase and the lucky owner (yes I am envious) asked me and to be honest I couldn't answer, even though i own, iPhone4, iPad3, a couple of Win7 PCs and an early Macbook all doing something at home (electronics repairs and HAM radio) which means I am across both Windows and Mac environments.
Of course obviously the OS has been loaded but what is that latest nifty Apple App, utility or major program every Mac Owner 'should' have on their machine other than Bootcamping a version of Win7. The reason I am asking here too is so I may receive a New Zealand point of view. TIA
