Guys, i think he was talking about the 15" recoil, which is a totally different chassis from the 17" one (because the 17" recoil don't have mechanical keyboard)
So, to answer to the original poster, for now, yeah, the 15" recoil is the only one to have a mechanical keyboard
But, what's still relevant is that the 15" recoil need a 280W adapter that weight roughly one kg
I have this laptop and IMO the mechanical keyboard isn't very nice. There feels like a variance in the amount of travel required across different keys, some needing so much that I always miss them when trying to type with any speed.
The power adapter is 75x150x25 mm and delivers 230W
