I hope they release the SDK soon (as in within 2 weeks) - its time for Entourage to speed things up a little bit here.
As an eDGe owner, I'm getting impatient for the SDK to be released to finally develop apps that are Edge specific. I am not complaining as a consumer, but trying to say that for the sake of the company they need to get their act together and get this SDK out already. Without applications for the eDGe, the device is suffering.
It would be nice if the source for the Library App was released too. I would love to work on that application a bit.
