What's strange on a mac is somehow having the ability to completely lose windows.

Another frustration is trying to view two apps together on the screen at the same time, if one of the apps itself contains multiple windows. I'm not at my desk to try this but let's say you have multiple chrome windows open, all with their own tabs, and you want to view your current chrome window overlayed on a window from another app. To do this you have to manually minimise all of your chrome windows one by one so they will all move of the way, to allow you to switch between apps and view them both at the same time.
