PB Tech have some new 16GB Class 10 MicroSD cards with SDHC adaptors for about $45. 

I bought one and it works great in my FujiFilm FinePix Real 3D W3 camera in the SDHC adaptor.  (I had tried a Class 4, but it was too slow to record 720p HD video.)  

This means I can swap the MicroSD between my camera and my phone to make the 3D pics available for upload from the phone without having to go home to connect to a PC.

It's a pain in the a*se having a disconnected camera, but at least these cheap and cheerful high speed chips provide a work-around of sorts.
