not much use to americans perhaps, but to those of us in Europe these people sell the mx 1000 already - mine arrived on the 06/09 after ordering 3 days prior at 2am
http://pixmania.co.uk/ that has a link to the localised version of the site clcik your country then just pipe mx 1000 into the search box and away you go
and btw - it is a very very nice mouse, not as heavy or clumsy as the mx700 wakes up to hand movement instantly rather that the small delay *I* had with the mx 700 and it arrived almost fully charged - usefull cos mine didnt come with a uk mains adapter and I overslept today so couldnt buy a plug converter before coming to work at 9pm....
it is worth every penny I paid for it. I'm very glad I bought it.
