The Sony SmartDock was initially announced for the Xperia ion at CES 2012 earlier this year. The multimedia docking station is broadly similar to LiveDock that launched last year for the 2011 handsets. It includes two USB ports like the LiveDock but improves on it by adding a HDMI port. Sony confirmed at MWC that the Xperia P will also get its own SmartDock. This will be the same feature-wise as the SmartDock for Xperia ion, but is made to fit the Xperia P.
The SmartDock for Xperia P can be connected to a TV via HDMI to watch movies, browse photos, play music etc. You can also control the phone by using a TV remote (as long as the TV is HDMI-CEC compatible). The two USB ports will allow you to connect a keyboard and mouse for a full PC experience. The dock will also charge your Xperia P too.
For those hoping of a similar dock being made available for the Xperia S, then we have some bad news. We were told by Sony Mobile representatives that nothing is planned so far. We imagine that part of the issue is that the USB and HDMI ports sit at opposite ends of the Xperia S. The LiveDock still should work, but obviously you won’t be able to benefit from the HDMI out.
