I think the ipad will only reach a point in which is has potential to push PCs out of the market once it no longer needs to be tethered to a pc for regular use.

I think the ipad will only reach a point in which is has potential to push PCs out of the market once it no longer needs to be tethered to a pc for regular use.. Keyboards, size, and general interface are all this people acclimate to, but only being able to move things to the ipad from a PC? You can't get around the necessity for the PC there. When the ipad starts to feel more like its own device, I could feasiblly see Wozniak and Jobs' vision becomming reality. But till then, its a dependent device with a great UI.
