So, this will work....
Just like Sony's UMD for PSP has been *such* a runaway success. Presumably they think that being smaller will somehow make them more likely to succeed, even though the capacity of the disc is so tiny. Optical formats with 50GB I can see working, Optical formats with 2GB? No so sure about them. Too small to be high def, not significantly more portable than UMD, nor inherently better in any way. Far bulkier than flash, uses more power on the move. Why bother?
