I just picked up a 16gb PNY microSDHC card, class 10. PNY part #: P-SDU16G10TEFM1
Confirmed working in the Transformer.
This is the one I got off newegg - PNY 16GB Micro SDHC Flash Card for Tablet PCs Model P-SDU16G10TEFM1
Here's the ATTO benchmark screenshot. The class 10 rating is accurate. I hit over 15 mb/s on writes and over 20 mb/s on reads
