Thanks for the article, Jens. It's great to see Cisco leading in the mobile collaboration space. Honestly, I was not a big fan of Spark--formerly Squared--when it was first offered. Now, however, I use it all the time for quick collaboration with colleagues, partners, and customers. It is wonderful for developing new ideas and for establishing "context" leading up to formal WebEx meetings. I can't wait to read Aragon's Tech Spectrum Report. Thanks again.
