The situation that you describe above was the same when 802.11 first rolled around as well.
You had to install a piece of software that came with the PC card. But that has changed with 
wifi now being an integral part of the notebook computers. 
And I think you could expect 3G chipsets and access built-in as well in due course of time. At least I know of a few
operators in the US (as well as notebook manufacturers) who offer such net/notebook computers,
i.e with integrated 3G access. I do not know what additional sw is loaded on these but at least the end user
is not installing anything else. 
Does it imply that such hosts will include the software that would enable host mobility? Its an open question (i.e unknown)
and will depend largely on operator choices and vendors.
