Where did I ever write about display resolution?
The retina MBP has very fast CPU and GPU (which you will only find in gaming laptops), weights 2kg, IPS screen with up to 1920x1200 resolution and has a very decent battery duration. Add to this list the industy-best tochpad and a 6KRO keyboard (where most laptops are 3KRO or even less). Windows laptops with equivalent hardware are either heavier or slower. An equivalent Sager weights almost 4 kg with battery life being half of the rMBP. I have no idea how you can claim that Levovo et. have faster CPUs where rMBP offers basically the fastest currently commercially available consumer CPU (3820QM).
Besides, with double TB and very fast WiFi, the rMBP offers potentially the best/fastest expansion options than any other laptop I am aware of.
But the retina display is resource-hungry and hogs the GPU and CPU so, no, it is not a perfect business laptop.
EDIT:

EVERYTHING is SOLDERED down!!! You'd have to be bonkers to thing it's even potentially the best expandible laptop!

Thank you for the simplest true answer. I was all pc in the 90's I was all mac in the 00's and since 10 I am mixed some mac and some windows. Frankly since neither one really cares about customer needs. As a customer you need to pick and choose and be more flexible then they are. Easiest way to be flexible is to be able to own and run both as needed.
Being a fanboy is the worst possible way to shop. either side will take your money and laugh behind your back.
Same. I use windows for gaming and for programs that don't run on OS X.
