I sorta live in all three OSX and Linux have the same type of file management. Spot light can be replaced with synapse and instead of alt+tab you have alt=F2.
In Windows I hit the Windows key and start typing..
I like all three for different reasons, but I dislike MS for their shenanigans in the 90's..
