What I think is funny, is that Apple has tried to encourage people to be their own content generators with things like iMovie, GarageBand, etc. People can't do those things with the iPad. The iPad (for the most part) relegates the user to just being a consumer.<p>In general though there will <i>need</i> to be an 'open' Mac for a number of things: audio editing, video editing, photo/video storage (I have 40Gb+ of photos and I only have a little point-and-shoot), photo editing, 3D modeling (for movies/design/engineering, etc.<p>This is not the death of the general purpose computer. Think of the number of amateur photographers out there, enabled by software like Photoshop/Aperture/LightRoom and the afford-ability/accessibility of DSLRs. Think of the number of people editing their own videos and/or music out there? They can't do this on an iPad. Granted, these people aren't a majority of the population, but there are a significant amount of younger people that are adopting these hobbies because they are so accessible now (thanks to the general purpose desktop computer).
