When Nokia released their Lumia devices, a feature that now is almost getting standard on other devices, was missing. The ability to share pictures, video and music to other network connected multimedia devices via DNLA. In the beginning of summer last year, Nokia brought DNLA support to some of their Symbian devices like the Nokia N8 via an application called Play To. Recently the Nokia N9 running MeeGo also got DNLA support trough the PR1.2 update.
Now the Play To application is coming for the Lumia devices as well. Still in early Beta for now, but it shows a promising start. With Play To you can share your photos and videos from your Nokia Lumia phone to your DNLA-capable devices over your WLAN network. This could be a DNLA supporting big screen TV,or maybe your Windows 7 laptop and desktop. Currently there is no support for sharing music, but this is something that will be added according to the developers at Nokia Beta Labs.
