Great point about telepresence-- please refer back to our newsletter last week on the topic. Here's the link for "Up close and personal with telepresence." 

If I can belatedly add a little analysis to the original telepresence mention: Telepresence is a great technology, but I think that many more enterprise users (by counting users and not companies) will benefit from Unified Communications than by Telepresence for years to come. Note that in my assumption, I don't count desktop video conferences or standard definition video when I consider this; rather a true Telepresence requires HD video and very high quality audio. Until the cost per user (including the costs of equipment and especially the costs of bandwidth) come down a bit, I think most users will stick to voice, email, and UC. As a "horizontal application" UC has a much broader and more immediate appeal. Your thoughts?
