I still think the iPad is far from being a stand alone device.
I've needed iTunes for everything - from the starting it up, through to transfers, to application downloads (20MB back in the day), updates to apps and even OS updates. I even borrowed a R201 mifi modem purely for the iPad to bypass the wifi restrictions.
I posted on the Apple forum that I needed a file for my PC ... and even with an iPad, mifi router and built in modem - there's nothing I can do. I couldn't access the file and don't even know where it is.
But like I say, I think you're the minority setting things up with iPads and PS3s - the majority of guys have the PC linked to their wifi, but I get the point.
