I'm currently using Logic Pro 9 on a MacBook Pro and am thinking of moving towards a Mac Mini-based setup. One thing I have been wondering is: Should I get a single 27" display, or rather two 24" displays side by side? I'm a bit old school when it comes to logic, I usually use the different window setups to switch between e.g. arrange view and piano roll view. I imagine having two displays would be really nice because it would enable me to have those two windows side by side. Any compelling reasons to go with a single 27" instead? Is anything substantially different in the window setup in Logic Pro X vs. Logic Pro 9?
