Anyone seen this TV ? Apparently it's an updated version of the 42WH18B due out imminently - only difference as far as I can see is "free to view iDTV" - anyone know what this consists of (calls it "Digital Terrestrial [DVB-OFDM]" under the tuning blurb)? Probably just the terrestrial channels plus the weather channel !! Surely there must be something else to differentiate it from the 42WH18B? Surprise, surprise nothing on Tosh website. Help would be appreciated - I've been offered this instead of the 42WH18B due to lengthy delivery problems.
