$2600 with base ram (not sure how much 3rd party to 32GB will cost) + Apple care + Taxes = probably more than you were expecting
Nope. About $200 less in total. I'm keeping the 8 gigs of base RAM, adding the i7, 1TB Fusion drive, the 680mx, Apple Magic Mouse and Trackpad combo and Apple Care. (Along with Apple Airport Extreme, Apple TV and a printer.)
About $3500 including taxes.
Will match up nicely with my 3rd Gen iPad and my iPhone 5.
I'm in the ecosystem not because I've been suckered in... but because I love the simplicity of it all. It just works and works well for my lifestyle.
