If someone feels that a 64 GB SDXC card is too expensive, they could put a 32 GB SDHC card in the SDXC slot and buy the 64 GB SDXC card next year when prices are much lower. The idea is to greatly increase the number of items that will accept SDXC cards so that the cards can become mainstream as soon as possible. As long as very few devices use SDXC cards pricing will remain high. Hopefully a year from now there will be 128 GB SDXC cards.
