Bluetooth = more battery consumption, Lags (Score 1)

After talking to several colleagues (we use laptops every day), my conclusion is: - Bluetooth mice use more power - Bluetooth mice sometimes lag or "pause" for a few seconds - USB Wireless has that thinggy that can break when you forget it and toss the laptop into your bag. Since I'm used to having my mouse ALWAYS NEAR my laptop, I've bought a CORD mouse from Microsoft, and it works pretty well and its much cheaper.
