I returned from Spain last Thursday. I was very impressed by the scale and quality of the conference. It was amazing to see how many people they could get to pay 600 Euro compared to a similar number of CTIA attendees at $50 a pop. There is probably a lesson in there for the CTIA.
I didn't have a whole lot of serious takeaways other than one over arching thing that I couldn't shake. The overarching thing was that the music is playing and everyone is looking for a chair and this is making for some strange bed fellows. Witness Microsoft buying Danger, Sony releasing a Windows Mobile device, etc. I think there is a lot more of that sort of thing to come.
For our part we announced a partnership with Bebo, one of the largest social sites in Europe, that you can see here as well as a with Moko which is a leading mobile only community in the UK which is here.
