If one is (like I am) looking for a Retina-like screen, there's only one option, the Notebook 9 Pro 15.6'' [1], which is quite bulky and has that cheap plastic look.
Thanks. That's a very underpowered machine (dual-core, 8GB RAM, 256GB SSD, integrated graphics), though. I neglected to say that I'm looking for a MBP 15'' alternative.
If you can get past the "gamer" aesthetic and you aren't interested in a 2-in-1-- the Razer Blade (and Stealth) are great build quality and specs. Razer itself has terrible (non-existent?) support-- but the products are good.
