Just got shipping confirmation on my 21.5" imac with the 2.8ghz i7 processor and only 4g of RAM...I may upgrade to 8g eventually but should be fast enough for my purposes...for now. I had the 2008 macbook and a 1st gen iPhone (Still works!), so I think once I get my old MB fixed and upgrade to the iPhone 5 next year I should be set up with an Apple trifecta of awesomeness!
