Not sure if you've seen our announcements a month or so again around Mesh. Mesh is our new platform for connecting people and devices across the web in a really seamless fashion.
Think of Mesh as a development platform for enabling synchronisation of any kind of data, application or information across the web - and the first implementation of the platform as what's visible today. So what can you do with Mesh?
In the past I've used multiple technologies to sync my docs and data between home, work and wherever - now I just use Mesh and I don't have to think about where my data is when I have to finish that presentation at home or the airport. My docs follow me around.
It's currently in Tech Preview but is proving a very smooth experience. It will be extended to smart phones, Mac and other devices in the near future.
Try it.
