Was looking to purchase the Casio 10MP Camera - Black (EXILIM).?

my question is i know it uses secure digital card but what do all the speeds on the card mean? also whats the average of pictures for a 2gb card. thanks

you need a high speed card to take movies with a digital camera.
2gb will hold 600 or more - depending on your settings.

black ones are cool

speeds are how fast they write
