I recently purchased a KDL 640 series tv with the understanding that the new Sony TV SideView application would work. Advertising for the app specifies that SideView woks with Bravia TVs with manufacture dates since 2011. It as well as the as the MediaRemote apps will not work. Using the remote as a keyboard for a Internet TV is not a user friendly option. Will the app or the TV be upgraded to provide this needed function ? The 640 series TV is a current Sony marketed product - highlighting its Internet capabilities - Sony should offer this support.
