I plan to purchase an iPad. The rep at the local Apple store told me the iPad was really designed to work with a computer. Unfortunately, if that is true, it will not work with mine, which is an old G4 running OS 10.4.11. While that is out of date, I doubt a new faster computer would do any better on dial-up than it does. I want the 3G 16GB version of iPad, primarily because it will allow me to get DSL service, which is not available any other way where I live. So what I want to know, basically, is why does it require a separate computer? What is it the iPad will not do?
