I personally think this updater is better (tried them both). However what I'd really like is an implementation like you have with the N900, which only updates when it detects a change in position, which saves battery life. I seem to remember having 1 minute updates on the N900 without adverse effects. Still on the N9 I can have 10 minute updates without big problems.

The real issue though is checking google latitude on the N9. I can't open the Google Latitude on the built in browser, nor on Opera or Firefox. Anyone know of a way to check my friends' location using the N9?
