Yup, I'm still running mine on an older driver version. I signed up with bullsh*t details, but found that the new driver was pants at any time, with the amount of calling home that it did.
So I won't be buying a Razor again. I don't find the tracking that good on the admittedly non-optimal surface I have, and the middle button is way too stiff. Also, since I have small lady hands, it's too big to be comfortable.
