Recently I've heard quite a bit about how the digital divide is shrinking because increasingly people have access to the mobile internet. I'm someone who a few years ago thought digital divide concerns were somewhat overstated, as the internet was not yet really necessary for full participation in the economy. I don't think I was wrong in that assessment then, but increasingly access to the internet is necessary.
Along those lines, most mobile devices ("smart" phones etc.) give you access to the internet in some sense, but not necessarily in the full sense that people increasingly need. Useful for the twitter and punching up the weather, not so useful for uploading your resume.
