I'm trying to use the card in SD slots. I don't like or want to use the
proprietary 'security', so I'd rather vote for MMC than SD. Then again,
I'm only seeing a couple of MMC vendors at pricegrabber and those look
like USB drives not MMC cards.

Guess my votes didn't count...

Digital camera. Currenly a nikon coolpix 5600 that's way slower than it
should be, I think. It usually takes several seconds before being able to
take a second shot.

I'm contemplating purchasing a canon powershot S2, so I want to make sure
whatever card I buy is appropriate for it as well.

The nikon is 5.1 megapixen and the canon is 5.0, so theoretically they're
writing about the same amount of data, right?

Ah, there's a number I can manage, danke :).

Yeah, at this point I'm happy to get a card that's faster than the camera
as I'm sure I'll be buying faster devices in the future :).

I've got a pair of 'normal' speed cards and I want to see if the card is
the difference. In the next few weeks I will be at events where I want to
be able to quickly take pictures, so I want to get a card now if it'll
help.

Using 2500 mAh NiMH batteries, so that shouldn't be the issue, I'm told.
Well, provided I'd properly listed what I have...

ciao,
