With iOS 5, the need to use a computer to sync with your iTunes account will not be needed. Technically, with the changes that will be out before the iPad 3 debuts, it will be more viable to eliminate a computer for many. Whether it is practical, is a different story. Unless all your media content comes from iTunes, you will be limited in what you can download. Some processes are just more easy to complete with device that will accept USB or DVD downloads. My suggestion would be to try going the iPad 3 route, but anticipate buying a basic laptop within a year after that. Even if you decide you do not need the laptop, you will have the money for other things.
