I know what you're getting at with the "get a new name" thing though, so I'll follow along. Yes, horses and cars are two different modes of transportation, and they do not share the same name. The only shared characteristic between the two in this particular case, however, is that they are/were used for transportation. Are you suggesting that "horse" came first as a mode of transportation and then they invented the automobile and thought "we can't call this 'horse', so let's call it 'car'"? Since there isn't really a generic term to classify a mode of transportation, I'll just say "vehicle" (for the time being). Cars and horses are two kinds of "vehicles," and they can be reasonably classified under that generic term as they both classify as modes of transportation. The analog of "vehicle" in this particular case would be "personal computer." Now an iPad (or tablets in general) can be seen as a type of personal computer that is reasonably classified under that generic term. The analog to a car and horse would then be "iPad/tablet" and "desktop" (or "notebook"), not "iPad/tablet" and "PC". And further, why do we need a new name for the "new" PCs when the current stable of PCs still fit the definition?
