You have 1.0? The tag on the spine of my edge says "Model: eDGe 2.0" ;-)
So far, I don't see a lot of deficiencies in the hardware. All the "problems" are gaps in the software. Entourage has already shown the software can be updated and has promised more updates. This, I think, is much better than other electronics manufacturers with devices that are totally closed and incapable of being upgraded. Many companies expect their products to be disposable and customer "upgrades" mean we all have to buy a bigger model.
