I really don't need GPS. another thing is I owned the Sport for a week last year and took it back as I couldn't justify the price. I always wanted to get one again and now is a great time but I don't see a single reason to get Series 2. I even kept the brightness down on that one week purchase I made previously! I want the concrete grey strap so to get that and the watch I could keep the cost down with S1. Anyone else not bothering with S2 and getting S1?
