Garmin Forerunner 305

I have been looking at the new Garmin Forerunner series (205 and 305). They look excellent.

"It continuously monitors your heart rate, speed, distance, pace and calories burned so you can train smarter, more effectively. It tracks your every move with a super-sensitive GPS that even works on tree-covered trails and near tall buildings. Receive a detailed post-workout analysis on the PC with included Training Center™ software".

However, I don't think that they provide you with details of your longitude or latitude / or grid ref, which seems like a major flaw... the battery life also looks a bit weak...
