Adopt the Right iPad Mindset - DON�T THINK OF IT AS A COMPUTER

Let�s get this out of the way right up front: the iPad is no substitute for a conventional computer. It may be tempting to think of it as a computer�after all, it has the same kind of display, processor, and networking capabilities; uses an operating system derived from Mac OS X; and runs applications you normally see on a computer, such as Web browsers, email clients, and word processors. You can trick it out with a full-size keyboard and other accessories to make it look and act very much like a computer. And yes, of course, if you want to get picky about it, technically the iPad does meet the definition of �computer�!

But if you think of it as a computer, you�ll assume it should do everything your Mac or PC can do, in the same way, and that simply isn�t so. Sure, the iPad can do lots of things better than a computer (owing mainly to its multi-touch display), but that doesn�t mean it can replace your computer. Even if the iPad could entirely meet your work needs, you�d still need a computer for a few important tasks�setting up your iPad initially, installing firmware updates, backing up your data, and syncing large media files, for example. So, let�s be clear that the iPad won�t replace your computer�it most likely won�t become the main device with which you get most of your work done. Instead, it will be a supplemental device that you use for certain tasks, or in certain situations, instead of your computer.
