I just checked with your sales department. Apparently, mobilME is locked to the 128 Mb USB drive that it comes on. This is a deal breaker for me.
I think more and more professionals like to have their favorite apps on a USB drive. It lets them be more productive as they move from computer to computer. So mobilME is a good idea. But locking it to a 128 Mb flash drive is not.
At least one of your competitors gives a free U3 version of their editor with the full version. I would pay a little extra for a mobilME version that would let me install on the flash drive of my choice.
