When I open the box to my new iPad and turned it on the screen displayed something like 'connect to itunes'. What if my needs as a user (and I believe many such users exist) could be completely met by the iPad. Would I still have to have another desktop or notebook to update, manage, and backup my iPad? I have read several discussion regarding the iPad replacing your laptop, or being your only mobile device, etc. and understand that depending on the user needs this is very possible and for other users not likely at all. And I do not wish to start a discussion here of the limitations of the iPad and why many users still need other devices and some don't.
I just want to know -
Is it possble for the iPad to be your only device? (A stand-alone device.)
If yes, ...
What would you do to get it running when you take it out of the box?
How do you update it?
How do you back it up?
