Hi All! Just to chime in, in case somebody could use the information about a card that works: I purchased a Patriot 8GB MicroSD SDHC (class 4) today, which came with both an SD and MiniSD adapter, for $24.99 from Canada Computers. Within moments of getting it home, I was filling it with data from my Ubuntu box, and it worked flawlessly in my N810. 8GB is very capacious! If you're looking for an affordable card that works (at least in one case), consider the Patriot 8GB Micro SD! I only post this here because I consulted the forum before purchasing a card (I was *just* about to by sandisk too!) and took a chance on the Patriot. I figure this information could help somebody looking for a card that works. YARR! }:^)~ Corrupt SDHC
