I bought a hi speed card reader to go along with the high speed ATP flash, so the MMC Mobile to computer speed will likely be useful. It gets surprisingly annoying transferring large files when you just know for a few more $s you could have been doing something more fun.

I am not too worried about whether or not I get full usage of the potential speed right away - I prefer to not have obsolete memory around. Also, since Fanoush has demonstrated the speed hack, the potential exists for it to become part of a future OS upgrade. If not, eventually, I will figure out how to follow in his footsteps.

The aspect which is les clear to me is if the MMC Mobile really puts a floor on speed as much as a ceiling. There appear to be substantial differences in specs between MMC Mobile memory card brands. I will do some simple testing to see if it was at all useful.

Last but not least, I use my 770 outdoors about 40 % of the time. I will happily pay a premium for electronics with extended temperature range.
