I am personally not content with 2GB. I continuously have xcode, IB, Tweetie, Mail, iTunes, Safari, Photoshop CS3, skype, 3-4 finder windows opened, with occasional use of preview and spotlight. And let me tell you, It swaps like there is no tomorrow...A LOT. I will probably upgrade to 4GB after I send it in for repair cause a problem I have with the hinge.
