2 GB uses new Maxwell GPU which is more efficient and more powerful than 4 GB old Kepler GPU, check internet to know more about it
and 1080p gaming rarely uses more than 2 GB GPU ram unless you are doing autoCAD then no point getting more
http://www.notebookcheck.net/Review-Nvidia...r.114908.0.html, Maxwell 2 GB has 10% more performance than Kepler
I am not so sure about y50 uses Maxwell or Kepler but I am pretty sure 100% a 4 GB GPU wont be any faster than 2 GB GPU GTX 860m at 1080p gaming
here is the proof 2 GB vs 4 GB
http://www.pugetsystems.com/labs/articles/...4GB-Memory-154/, and heck 2 GB perform better than 4 GB
2GB VRAM will never perform better than 4GB VRAM. It's like saying "4GB RAM is smoother than 8GB RAM because I only needs 3GB RAM", which is theoretically impossible.
And also, upcoming (as well as recently released) AAA titles are going to eat more and more VRAM. Reason being they will be built based on the latest consoles, which have more than 2GB VRAM (or Unified Memory). So the extra VRAM will come in handy IF by any chance the future games at medium~high settings need them. But I would have to agree that for currently most games won't need more than 2GB VRAM.
Anyway, the two points you stated, are actually optional and subjective to personal experience. Some users prefer a pure red backlit keyboard instead of the more fancy multicolour one. Some users prefer a slimmer laptop because they didn't need one, or if they needed one they might prefer an external one (Samsung's external DVD drive is cheap and good).
To me the most important aspects of a GAMING laptop are performance and cooling, which both are ticked by Y50, at a cheaper price than GE60 which has a worse cooling system. The tradeoff is a worse screen but then I'll get a much better looking slim design (again, this is subjective) so yeah it's a fair trade, imo.
