There was a Sandisk product flyer in the box my 7135 came in. On the flyer it shows a Cruzer with a SD card inserted into it which implies it is a card writer. But when I go to the www.sandiskstore.com website and look up the Cruzer it says nothing about writing to SD cards. Instead it gives me the impression that its a storage device itself since there's different sizes you can buy, 32mb, 64mb, 128mb, and 256mb. If its just a card writer then why does it need to have storage on its own? Are these guys just really bad at writing a product description or am I missing something here?
