There’s nothing particularly exciting about memory cards. The only purpose they serve is to store data for your favorite mobile device. Panasonic is doing something a little different with their microSD cards, however, giving them a little extra versatility by apparently packing in not only a standard SD adapter, but a miniSD one as well.
In this way, there is no need for you to buy additional miniSD or SD cards for your portable electronics, because that fingernail-sized microSD card will be able to do it all. Capacities to be available range from 128MB to 1GB. No word on pricing.
