Skype may be the Microsoft's communications tool of choice for consumers, but Lync gets the nod for Redmond's enterprise clients. The new Lync app has been "reimagined" for the new Windows 8 UI, which means the capable communications app is optimized for touch, and features the sleek, clean look of the interface formerly known as Metro. Lync users can switch between IM, video or voice conferencing, or use all three at once. A free download from the Windows Store, the Lync app also snaps to the side of your screen, which is handy for referencing a website or another app during a demo. Lync requires Lync Server or an Office 365/Lync Online account to work.
