The risks are, of course, higher, as they are with any increase in technology. Proper design should deal with that problem. Replaceable cells would obviate the possibility of a shortened lifespan for the card.
If it gave me the possibility of much higher write speed for a slightly higher price, I would definitely be interested, as would many people. m -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
