My question....will the N800 support SDHC. If so, then you can get into some serious storage with 4 GB out and 8 gb's coming.

One other thing that was not clear is does IT2007 also support a swap file? If so, I'd put that on the internal card.

Also, theoretically, you COULD mirror the cards if they were the same size. This could provide for better read/write performance if something like that is done or even possible.
