I assume your estimates of how hard it is and how fast the Outlook team can develop are completely ex-recto.

Here's some data. Outlook's last two major releases were in '03 and '06. In those 3 years they added the following visible features:

  - todo bar

  - better calendar UI

  - RSS aggregator

  - search

Xobni might be as useful and interesting as all those combined, and the Xobni team can deliver it today. The evidence suggests that Microsoft would take years to deliver something similar.

My estimates weren't ex-recto as you said. I took a brief look at Xobni, and thought that even I could have done it in a few months. Then a few engineers from MS could do it even more easily.

You underestimate corporate overhead.
