I'm thinking about getting an iPad. Currently I have an iPhone 3G, a Mac Mini, and a gaming laptop. I'm in love with iWork on my Mac, and was thinking of getting a 13 inch MBP to have iWork on the go, but now I'm thinking of getting an iPad. Is an iPad worth it if I already have an iPhone and a Mac? And how are the iWork apps on the iPad - specifically Keynote and Pages?
