Glad to see they're out. I've been holding off on my purchase until the new drivers were available but I guess there's no more holding out for me any longer.
Well everything is working well and there are a ridiculous number of conifguration options for my MX1000. The only problem is that some of the configurations are a little bit confusing. Otherwise rock solid!. Good job Logitech.
The best combo that I have been able to use has been a MX1000 with a Apple Bluetooth keyboard.
