in contrast to interfaces i will use the term devices for super-cool technics like an iphone/ipod touch, nokia communicator etc... which provides internet access where ever you are, which means you are carrying the web in your pocked (i guess a quote by an apple engineer)
most of these include some calendar applications, e-mail apps and webbrowser and much more, so actually you are able to surfe the net - just like on a laptop - on the bus, in classroom, at a friends place, in a bar or on the toilett, reading news, latest blog entries, check dates or lecture information and even download documents - brave new world!!!
to stop infiltrating your consumers mind .... there could also occure some technical challanges - as you need data for all sorts of operating systems ....
some studies show, that people who are useing this kind of devices are more active in microblogging or blogging anyways....
