I really like Xobni too. I use it at work and it does make Outlook much better -- primary because of the better search and threaded conversations (the social networking and analytics features are less useful for me, though). However, I think Xobni's market is largely hypothetical, and it's not clear how Xobni can make money. The fact that I have a credit card doesn't mean I will use it in Xobni, especially because the app is free and it already solves my Outlook problems. (Btw, I would be happy to pay $20 for Xobni if they charged me for it :) )
