I heard rumors that it would be included with iOS 4.2. Is that still the case? Currently, I have a MBA, iMac, and iPhone. I am thinking of getting an iPad, but can't decide between wifi and wifi +3G model. I think wifi only would be sufficient. Would I get enough use to justify getting an ipad with everything else I have?
