I think "useful" is in the eyes of the beholder, and correlates to screen choices. Wikipedia truncates some entries on smartphones, which drives me crazy... so I just wait until I've got a bigger screen to read it on. So I'm not the type of mobile user you need to consider - I'm easily irritated by sites on that little screen, now that so many small, portable tablets are light enough to carry in my bag every day.
But I'm not a 20-something who's happy doing everything on her phone. She likely wouldn't know the entries are truncated.
So, I think SO MUCH user testing is going to be needed to get a good idea what's going on with all this. Maybe in a year, the tech options will settle down a little, too. For example, I'm thinking about dumping my smartphone for a pay as you go and using a cellular-equipped tablet for mail and browsing.
