Regarding Web 2.0 it is as commonplace as TV and radio, indeed I'd say it has almost completely replaced TV for some of us – this is not generational or even specific to a cohort, rather some prefer the online environment to the many others on offer.
In our family the Internet takes precedence over radio, newspapers and magazines. For my personal learning environment PLE I now include the hardware – over the last two years I've gone from clapped out Mac laptop to an iPad: I keep everything online. If I need a laptop or desktop I borrow. My Smarthpone is my 'university in my top pocket' and some. I have a Kindle too for all books, even replacing some I have as hardbacks, while PDFs go to the iPad.
I will preload the Kindle with ample reading as this will go to the beach while the iPad stays at home (cottage).
