Jayvis - im not sure about the dual monitor support but im sure someone here can answer this for us ... what about a mac mini bro?
When you switch over to apple you really have alot less worries - no real worries about catching new spyware or virus that is floating around that auto installs because of windows
ive had an imac for years - never had to take it in ..only thing i really do is run a a program called CleanMyMac about once a week
