It's a bit too absolute of a statement IMO, but some of the comments here elaborate on his work in Android and iOS:
http://esr.ibiblio.org/?p=3554 The GIF and PNG stuff would apply to "using a Web browser" or "play on a game console" in general.
Here he says gpsd is used in Android: http://esr.ibiblio.org/?p=4886 . Anyway, that could be "locate yourself" in general.
Don't really have any ideas about ATMs. Maybe using gpsd for time from GPS? He's talked about that on his blog. I don't know why ATMs wouldn't use NTP as they're probably already fairly well-networked, though.
If I were going to say this, I'd cite carefully to avoid looking boastful. To each his own. It does seem fairly well-supported if you do some research. Here's his list of projects he's touched: http://www.catb.org/esr/software.html
