I think that moving towards higher-rez screens was a great move, and I personally can't wait for a 4K macbook...it'll be my first Apple laptop, and I'm pretty confident that Apple will break the low-rez ice with it.
It's very sad to see new 17" laptops being sold with 1366x768 (widescreen 1024x768) in 2012 to people who don't understand anything about computers.
Personally, I can't stand 16:9; I still have 4 24" 16:10 1920x1200 monitors, and I'll upgrade to 4K when they drop below about $800 each.
Edit: to point out that vertical resolution is very important, hence my really badly missing those extra 120 vertical pixels lost in the move from 1920x1200 -> 1080P.
