I use a Jabra BT250 headset with my PowerBook, mainly to use Word's nifty audio notes feature. Since I don't need it all the time, I keep it powered off when not in use. However, on 2 occasions, Mac OS seems to have "forgotten" the pairing, and I have to go through the pairing process. Has anyone else experienced this? Also, had anyone use Microsoft's Bluetooth mouse? Does it work with the IntelliMouse Mac drivers that come with its other mice? I bought a Logitech MX900, and while overall I like it, the inability to use its full potential (faster tracking, programmable buttons) kind of limits it use. Why does Logitech have such poor Mac support, I wonder? At least I can get the Exposé mouse button options to work.
