Someone asked me to develop some Android apps ... and so I have an android "nexus s" here to play with. In general, I don't like it --- it's certainly not worth $499, but that's not what the subject says...

... it does, however, figure out it's GPS data fast. I know it (like the n900) does some interaction with cell towers to get an initial estimate --- but it also get's it's more accurate lock _much_ faster.

... it also seems to me that the android turns on it's GPS antenna fairly often and that a cron job on the n900 could be useful for this, too... because turning on the antenna often keeps it "warmed up" ...
