Pros: Nothing significant to add other than what others have already said. CPU is a margin faster than the 4702, but uses significantly more power and heat. Dual graphics are the big crowd pleaser here. Sturdy, backlit keyboard.

Cons: Know up front that the one single difference between this model and the upgraded model they sell with the SSD drive is that despite the motherboards being the same, Lenovo has INTENTIONALLY removed the M.2 adapter plug from the second bay in this model. It's still labeled "SSD" in huge letters, has the screw holes for the adapter, and the solder pins are all there but there is absolutely nothing whatsoever you can put inside it. Either their profit margins are SO incredibly low it's difficult to believe they're still in business as a company saving on penny engineering, or this was an intentional giant middle finger to their customers. I'll leave it up to you to decide. Either way, you're going to be stuck with a single 2.5 inch SATA bay.
