I am soon to be getting a MacBook Pro in about a month. Since I have always used PC's, although I am very excited, I am trying to gather all information possible to make the switch easy and be productive on the the new MacBook. I have a simple question, I know on windows when you have many things running at one time it tends to bog and slow down. Running things in the background are the issues I am getting at. Does running application and widgets in the background of a MacBook cause them to slow noticeably? Thanks ahead of time.
