Nix Stress When Switching to a Mac

I cannot wait to switch from a PC to a Mac, but one tip I just came across is this:

One big mistake switchers make is learning the Mac on the job. You don’t want to learn something new under a load of stress. Set aside time to learn how the computer differs from Windows. Also, make sure to actually “quit” out of a program. Closing the “window” won’t do it!

Good to know, right?!
