"Given iPad’s success, tablet PCs dominate many investor conversations, as it has created the potential of a fourth consumption device (PC, phone, TV and now tablet)," writes Goldman Sachs analyst Sarah Friar.
Microsoft seems to believe the tablet is simply another form factor for the PC. Apple perhaps doesn't agree, and maybe doesn't have to worry about which view is correct. If all Apple can do is make the absolute-best tablet PC, then it wins. If it uncovers the fourth media device, and executes, it also wins, and maybe wins even bigger.
But it is hard to see how Apple can lose, at this point. The bigger question is whether anybody else can win, and if they can, how big they can win.
