I am currently a PC user and sick of viruses! I went to a MAC store a week ago and fell in love! I would much rather use two fingers on a touchpad than right click!!!!! I went into see a MBP - and I love it and surprisingly fell in love with the iMAC 24"! Now I am totally confused - I know both serve different needs. I am diabetic and do like a large screen for my vision. Is the MBP capable of supporting a 27" or 30" monitor? Do I need a special connector? Does the MBP have to be open to run it? Thanks!
