I can't believe this hasn't been on Slog yet today: Apple has sued Android phone-maker HTC for infringement of 20 patents.

For some time now, Apple and Google have been pals—until recently, they shared board members (and Al Gore has an advisory relationship with both companies). But with each company getting into the mobile phone market, things have taken a turn for the nasty. With Apple attacking Google's partners on one side, and Microsoft and Rupert Murdoch hammering at Google on the other, things are getting very interesting for Google, which looked invulnerable a few months ago.
