As a teaser, here's a snapshot of me testing Lync with Rich with Mary Jo Foley of "All About Microsoft" ZDNet fame in the background:
I hope to write a full review of Microsoft Lync soon. Although the virtualized images Microsoft sent me expired and want me to "Activate Windows" now. Doh! They only had 3 days remaining when I first installed them. Not good... I'm sure I'll find a workaround though.
