I bought SIIG's 11-in-1 adapter as it had the best price. I'm wondering, though. if the advertised numbers on the various cards is true. Some are 18-in-1, 11-in-1, 8-in-1, 5-in-1, etc. But it seems to me the higher numbers just include variations of the same standard. For example, MMC, RS-MMC, MicroMMC, etc. Same goes for Memory Sticks. Am I correct or do some of the cards really support more standards than others?
