On their site it says the software can control "D1 Airs with a USB Air Remote" nothing exclusive to the 1000's mentioned. I however, cannot get that software to even launch (though I don't have the USB transmitter). Has anyone actually used it?
And yeah, I really liked the D4 but do plan to wait for an Air equipped pack. The weight is kind of a drag, compared to Acutes, but, Man, the control you have! Nice.
