. There are a number of types of flash memory cards available, such as SD, CF, XD, and memory stick. Is there an advantage to having multiple standards or would it be beneficial to consumers if there was only one flash memory standard, such as just the various sizes of SD cards? Would having a single standard be less expensive and more convenient for consumers? If so, will a single standard naturally evolve or should it be mandated by the storage industry or the government? If you use multiple types of flash memory cards with your devices, would you prefer they all used the same type? Why or why not?
