I think the problem with the SD range has been the poor quality of the bundle. You get the camcorder, and the simplistic and constrained Panasonic HD Writer application. Nothing else. No proper PC player for the clips you can easily pull from the SD card. You appear to be expected to own a BD or HDDVD player, or to plug in the HDMI lead (which isn't even supplied) to your HD TV to play anything. That's the first thing they have to sort out...
At least the recent post about the Sony AVCHD bundle demonstrates that Sony have made the same mess of AVCHD introduction.
