joker97: Does bootcamp run from osx or boot separately?
Bootcamp Assistant creates a properly formatted USB stick from a windows ISO or CD, It puts all the mac drivers and stuff on the stick, yes it installs as a dual boot system. There are other options like VMWare and Parellels if you want to run windows inside OS X
You won't get the nice scaling features of OS X - basically you'll either have to use the max native resolution for it to look any good, a lower resolution will be fuzzy as you'd expect. OS X has scaling intelligence to make it look good even at lower resolutions.
Many older apps have issues on non 100% desktop scaling IME with my laptop with a QHD screen on it. Text going out of buttons and menus hiding behind other things. Something to look out for with high res screens.
