Hey, I've got the current bluetooth apple mouse... i love it when it works! With new batteries the thing still lags from time to time, often enough to be considered unreliable. No other bluetooth accessories... off a mac pro which is just four feet from my mousepad. Otherwise i'm stuck using a logitech wireless mouse, with a usb receiver, that works reliably but the tracking sucks... the apple mouse's trackeing is spot on for me... Any suggestions on either: -how to get my apple mouse not to lag -how to get my logitech mx revolution to track like the apple mouse -what other mice are comparable? thanks, r.
