ps
SDHC cards (4GB plus) are out for the 7K since they use a new memory mapping configuration (and will not work with SD card readers), but transflash (micro SD) and mini SD are perfectly useable since fully comply with the SD specification and the SD carrier they slot into is just a contact transfer housing. I've used a 512 mini SD for years as a working card in the 7k since could swap it (without carrier) to a previous mobile phone at the time.
