This may be a REAL dumb question, but I feel like everyone else knows the answer but me... Is there a difference between SD and SDIO? I would have thought that SDIO (Secure Digital Input Output??) simply means transferring data to and from the SD card... yes? But surely just a plain old SD card would allow you to read and write to it too, wouldn't it? Otherwise it would have been a pretty pointless medium.

There must be something more to the meaning. Otherwise, what would all the fuss be about regarding the Viewsonic being SDIO capable (or not)...

Cheers,
Alex

peripherals such as, say, a modem or bluetooth card in sdio format can work with an sdio slot, but not with a plain jane sd slot. so you'd be just limited to memory and sd media with plain sd. whereas with sdio you'll have a wealth (eventually (speculation)) of peripherals to choose from.
