man!!! here i was with my hopes up, seeing that there were new posts in this thread, but it's not too much "new" information. doh! i'm jonesing for this device more than i was for the MicroTrack (before it came out).
assuming the R-09 and SD cards require roughly the same amount of space for formatting the memory card, then you'd get the following with a 2 GB SD card:
3 hours 8 minutes at 16-bit
2 hours 5 minutes at 24-bit
hopefully the unit will accept 4 GB SD cards out of the box, or with a quick firmware update. not that 16-bit is bad, but it's nice to have the option of recording at 24-bit without physically swapping out memory cards.
