I saw on gpscity.com they have a Spot 3 for preorder at $149. The reason I am considering the Spot 3 over the 2 is because you will be able to use a USB type exterior power source to keep the unit charged while on the bike. Would come in handy if you have the tracking feature updating your position ever 5 miles or so. Anyone have any other information on the Spot 3? Best place to buy etc? I don't suppose they will be offering any discounts for awhile on these units..
