congratulations.
you will find macrumors a great community, you have kids here who are still in high school or middle school who know a whole lot about their macs and programing, you got your poor college students strugglying to get by, then you got your young and not so young proffesionals, and some unemployed ones. everyone here is generally friendly, and pretty knowledgeable, you may find yourself with a ton of questions in the begining, but before you know it you will be answering questions for the next switcher.
