Well one thing I notice is conspicuously absent here is any mention of 'UMD' With Sony's PSP - this is a new disk format which I interpret as an evolution of Hi-MD. Physically the disks are very similar. A UMD can hold up to 1.8Gb of data. Principally utilised for games disks or video there is no doubt the potential is there for much more than this. Initially Sony have closed the UMD pressing so that only Sony and their affiliates could burn UMD's. This gave them the lead on the growth in pressing UMD titles. And UMD sales are rocketing. Now, however, at least one rogue disk manufacturer has somehow circumvented this and produced their own UMD disk without Sony's consent (for some Japanese porn or similar). Ergo there are 'UMD burners. Extrapolate this a little more and we have the possibility of a portable UMD burner that becomes a partner to the PSP UMD drive. In my imagination I would like to see a portable UMD recorder that I can put data, music & video on that I can then play via my PSP. Of course this would have all the facilities currently offered by Hi-MD and more. This is/would be the next killer 'MD' derivative application. Sony can capitalise on all manufacturing plants geared for MD production by converting them to UMD. What do you think?
