* No issue using user interface when you are sweaty, unlike the Garmin 410..
* Heart rate strap feels nice and comfortable.
* Very easy to read dials.
* Very well built, I have no issue with the finished quality (doesn't feel cheap, unlike other manufactures, looking at you Garmin 205,305).
* One of the longest battery life for a GPS sports watch.. Which may be handy if your camping for a extra long weekend with no charger.
* Link to PC isn't using some third party dongle, I prefer a cable then a third party dongle which you can easily loose (Garmin 410).
* If you have a small wrist, like my girl friend you will struggle tightening band.. For me it isn't a problem and is nice and comfortable. Lets hope they come out with another design for smaller wrist people.
* Software to analyze runs is on website, so you need internet usage to view (my internet at home is woeful).. I am not that keen on doing this, but seems to be the trend things (Nike+, etc) so I can live with small disappointment.
I have minor issues in the software, such as not being able to zoom into single points to read pace at a point in time.with graphs not allowing point zooe are not easily zoomed in and points analyzed. I am sure they will improve this as time goes by and they get users feedback.
* Unable to use my polar heart rate monitor, so added expense of buying compatible strap and they are not cheap.
* Seems a little expensive compared to the basic models of Garmin .. If you only wish to know basic information such as pace and distance then you might wish to go for a cheaper Garmin (110). But after faulty Garmin 305 and Garmin 410 that you can't control once you sweat, I will be staying away from Garmin for a long, long time..
