There are now some 64GB and 128GB SDXC cards available...this is the successor to SDHC with more address bits. The current generation is electrically compatible with SDHC and just needs software changes (if that). Has anyone tried these cards in an N800 yet? The N800 has two full sized SDHC slots so it would be possible to install 256GB of flash, which is pretty awesome... the cards are quite expensive right now but of course they will drop.
