Because SDHC works differently (supports the new higher capacity cards) this new card format is not backwards compatible with legacy SD format host devices.
This was previously available at Amazon for the same price, but Amazon have since increased their price.
Make sure your device is compatible with the HC cards (older devices will only work with standard SD cards up to a capacity of 4 GB). The SD card-reader in my PC tower does not recognise SDHC cards, but the photos transfer fine when I connect the camera directly to the PC. A USB SDHC card reader would overcome this problem.
