It is pretty hard to see how anybody could be enthusiastic about caddies. At least anybody who actually used them. Caddies suck. Yes, they add protection, but at the same time they add bulk, hassle and cost. Caddied/Cartridge media has either been dying a painful death (VHS, mag tapes) or has never really been born (mini-disc, DVD-RAM). Sony and Philips have a long history of pushing dubious formats out the door (CD-I anybody?) or crippling promising formats with protection technology that limits its usability (mini-disc, lame sony attempts to market non-DAO CD-R units). Despite people's enthusiasm, and the idea that 'it would be nice' to have something that's high definition, I don't think blu-ray is going to fly as is. Come on, different PC and consumer appliance formats?
