I'm thinking of selling my iPad 3G and replacing it with the 11" 128GB MBA. I know iOS 4.2 is right around the corner and with that comes multi-tasking, folders, printing, etc. --pretty much making the iPad a lethal piece of portable kit. However, I've been charmed by the sexy-sleekness of the new MBA 11" offering. Am I becoming consumed with superficial gadget-lust or would having an MBA as an iPad replacement be somewhat logical? On battery life alone, I know the iPad 3G's 9 hours decimates the MBA's 5 to 5.5 hour battery life.
