A couple of plugs for cool things I've found recently:
Google Maps Mobile: a version of Google Maps for PalmOS. The only complaint I have is that it requires a wireless connection to work ... which is fine if you're on a mobile phone running PalmOS and have a network subscription, but sucks if you're on a stand-alone device. But this is Google ... I'm assuming they'll find a way to allow you to cache locations/routes/etc. offline.
