A couple of interesting things in the news regarding UC at the moment - firstly there is a lot of noise at Microsoft regarding the fairly imminent launch of roundtable.
Mark Deakin has a fairly good round up of the technology - but a visit to Tom Keatings blog is a must if you want to know more about the technology. At a cost of around $3000 this is going to be ideal for small to medium sized businesses, and it will be interesting to see how Polycom react to this!
Secondly Slashdot have an article showing the value of presence technology. I cant wait to see presence start to be embedded in more technology, and the value will start to become really apparent. Already people are starting to ditch "normal" phone in favor of soft phones - again head over to Mark Deakins or Julian Data's blog.
