It would not allow me to log in with the Edge at all since I have an account already and have my Phone on it. It only sees the handset from my PC and right now that I could see there is no way to add a device to your account other than to download a program to it, so yes a bit stymied, and a little let down, but not a deal breaker. I have to admit I have been using the AppBrain App for my phone which essentially does this very same thing, so while glad Google is getting busy, the functionality is not all that new. Except for in app purchasing..that IS a new one...not sure I want to let that one get out however...heh heh heh.
Oh yeah the link for those curious about the now redundant Appbrain:
http://www.appbrain.com/ Also NO I NEVER purchased an app anywhere outside of my handset, I only used this app to manage, update, add new free apps, or update my existing paid ones.
