Got one of these PNY 32GB SDHC cards from Amazon for my N800 yesterday and installed it in the external slot. I have a 16GB Class 6 A-Data card in the internal slot. Loaded up around 5000 mp3s across both cards. The native media player pretty much chokes (sluggish performance, refreshing the library takes forever) but besides that, everything appears to be working as it should.
