People who aren't even aware of thunderbolt eGPU on Macbooks are hardly qualified to compare specs of different laptops and enforce their opinion as facts about what's better (Dell XPS, Latitude, Lenovo Thinkpad, MS Surface, MacBook Pro retina, Razer Blade, Alienware, VAIO Z - all have advantages and disadvantages, but if you don't consider the whole package it's just pointless). I'm sorry, but most just have no idea. And then there're fanboys and anti-fanboys, so trust me - most of the info you'd read here is useless.
