I got my Oregon 550T today.
I Ordered it from Amazon and got it from the PO today. I got the GSAK Macro for the Colorado/Oregon and loaded 4,915 caches along with descriptions. Once I had the Macro installed it took a minute or two to load it. I like it already. Here is the first picture I took with it.
The quality of the picture seems good. I took the picture out the open window of my car while it was raining . Shewolf and I will probably head out with it this weekend and put it through its paces. Not much hiking though. It's still too hard on my foot. I already like the idea of not having to take along my PDA and camera.
