Hello, I really want to switch to macs. I have a 4 year old Dell PC and need something new (and cooler). Anyways I really love the cinema displays, I know they're expensive but they are awesome. I want to get a refurb 2.2 ghz blackbook and then a 23" cinema display. Is this an ok idea? I just do the basics and encode and download movies, etc. I would put my RAM into but I just don't know how all this would work together as I'm new to the world of macs. Thanks !
