SanDisk Spins SD/USB Flash Combo
An anonymous reader writes "Flash memory pioneer SanDisk has created an innovative memory card packaging technology that enables memory cards to plug into both SD card slots and USB ports. The new approach eliminates the need to use SD-to-USB adapters when accessing the contents of an SD card on a laptop, PC, or other system that lacks an integrated SD card slot."
How much more expensive are these going to be than normal cards? USB reader dongles can be had for next to nothing these days!
how large does a usb key have to be- could it be made to go within a camera?

Avoid SD cards at any cost. The wide adoption of SD (which means Secure Digital, and not SanDisk) is the next step towards putting DRM control around our data.
More info are contained in the official SD and SDIO complete reference, which -surprise- is neither open nor free, and costs big bucks/NDA signing to get.
My answer is thanks but no thanks, I'll stick with more versatile, cheap and open supports such as Compact Flash.
That was my first impression but after thinking about it I changed my mind. Most users are only going to have a few SD cards. Usually just the one they have in their camera and maybe a spare. For these users having an integrated usb reader is very convinient especially if you are on the road and want to transfer pictures to a friend's computer. With regards to cost as you pointed out USB readers are pretty cheap. It probably costs next to nothing to add the USB bit. (A quick check of a local shop shows SanDisk SD cards are just slighly more expensive then similar USB drives.) I would guess that there will be a higher markup for the convinience factor, then the cost of adding the USB.
If these USB/SD cards become popular I predict that some camera maker will drop the USB interface from their cameras.
Don't discount the convinience factor. For a few bucks extra I would by a device like this. If only so that I didn't have to remember to bring the card reader.
