"Convergence" is a word I've heard plenty of times in the last 10 years, when mobile phones still had monochromatic screens and Minidisc players were all the rage.  Now, with Google and Apple entering the mobile market, it's definitely getting interesting.  The IHT has a run on the situation here, and a couple of posts from Mobile Opportunity giving a digest of the most recent moves here and here.

Disclaimer: Yes, I work for one of these companies, but even if it weren't related to my job I find this interesting.
