Apple has touted the iPad 2 as a "Post-PC" device. They said it in the keynote, they say it in the official iPad2 video. How can this be if you NEED a PC to operate it? I am trying to convince myself that I can use JUST an iPad when I go on months-long trips and sell my Macbook Pro because I feel it may be overkill- but I am questioning the "post-PC" label. How do you take it -- do you think Apple intends that phrase to mean it can replace a laptop or simply it is a whole different world than a PC because of its form and iOS?
