LOL for 10 years (hard to believe) and you still don't know the shortcuts to windows? Ever heard of right click on the task bar and select windows side by side? Or just grab the app and slide all the way left/right until windows re-size if for you.
What i meant was under a PC, i find myself only productive when I have 1 window opened per monitor. Try it out yourself, have a bunch windows opened on a PC and a mac, and compare. In osx, feels like you have a stack of documents you can flip through; in windows, there's just a bunch of windows that you want to maximize each one before using them... Maybe its just a personal thing.
