October 26: It's the day Windows 8 and Windows RT tablets and PCs are available for retail purchase. It's also the day that a number of Microsoft-developed apps for the new platforms are downloadable in final form.
The Lync app, to which Microsoft officials previously referred as Lync 2013 MX is a touch-centric, Metrofied ("Windows Storized"?) version of Microsoft's Lync unified communications client. Lync 2013 MX was not released as part of the Office 2013 Customer Preview in July. The new client is compatible with both Lync Server 2010 and Lync Server 2013. It includes Skype federation, meaning Lync 2013 users will be able to see presence, instant message or call anyone on Skype.
