Clare Newsome:The Panasonic's got a slightly better TV tuner, sounds a little better and is, obviously, two inches bigger. The Sony looks punchier and its Motion-Flow system is smoother and more natural than Panasonic's IFC. Your choice...
Corect me if I'm wrong, but you can turn the Panny IFC off and motion handling is still spot on (IFC smooths out 24p playback, if you like that sort of thing). Whereas you really have to have the Sony Motion plus enabled all the time. So how does the Sony handle sports (footie, rugby...)
