Right, but the question hasn't been about SD vs MMC, but SD vs. SDHC. MMC I think is pretty much gone. I haven't seen it around since last year at least. So the distinction isn't too important since I don't think you can even buy them. However SDHC came out late last year and so a lot of devices that people have now (which were designed a year ago or more) are not compatible with it. Luckily some devices, like the Treo 700P, can remedy that with a hack or firmware upgrade. But it's unlikely you will see such a solution for a compact digital camera for example, since manufacturers never seem to come out with firmware updates for them, just for the more pricey DSLR's...
