Thanks for the tip. I don't need one yet, but now that I know they're in the wild, I can watch for them for future needs.

Ok guys, heres my noob question.
The N900 is advertised as having expandable memory UP TO 16gb. Is that just a suggestion? Is there not any reason it can't handle 32gb? Did Nokia advertise 16gb as that was the largest memory available?

Sandisk released their 32GB card today... $200 US though. That's kinda pricey considering their 16GB card can be found for $50 US.

Also, the 32GB sandisk is class 2

The problem is density - with current fab processes (and I suspect for a while still yet) to get 32GB into a uSD you need to use MLC flash - which is slower (and less reliable) than SLC (which takes much more space). Thats why you dont get 6 speed 16GB cards either.

Wear should only matter if the memory is at the end of it's read/write lifespan.
On write speeds it's worse than harddrives. If you write 4k to sd card, the sd card must internally read 256, change 4k of it, and write it back. Take 256/4 and you get the slowdown factor. Obviously, writing 256k for a 4k request means the flash is taking much more wear.
