When you compare Mac OS to "Mobile" OS styles, you can see that the interface was clearly designed for the platform. Like somebody said before, you don't want to have to resize windows with your fingers, or try to click the close button and click minimize instead. The buttons on the mobile OS are big and spread out.
But this is where my dilemma comes in. If I have a desktop, a macbook and and ipod touch - where does the iPad fit in? It's no replacement as Apple made very clear; it's a whole new category. So as great as it looks, I need a portable machine that also runs the OS I use at home (which, as I've said already is not a good idea at all).
