Suppose Tim Cook came out and said, "Here at Apple, we realize that tablets are the future of computing. After all, nobody likes carrying around a five-pound computer. So today I am happy to announce that we are replacing our line of MacBooks with a line of fifth-generation iPads. The processor on these new iPads will be fast enough for most MacBook powerusers, and the graphics will be good enough for most intense gamers. Now, you may be thinking, "What about the CD/DVD drive." We've got you covered there, too. For $50 you can buy a drive that allows the iPad to watch and create CDs, DVDs, and Blu-Ray discs. Another question you might be asking is, 'What if I want to plug in my other Apple-created mobile devices.' You don't need to. That's what iCloud is for." How would you react?
