Which Mouse should I upgrade to? I currently have a Microsoft Wireless Mouse 5000. It is very precise, but I hate the way the wheel works, sometimes it goes fast, sometimes slow, no matter what setting I choose in the settings, after every restart, that changes too. I have the latest drivers for x64 for it. I have read online reviews that its wheel is funny and doesnt feel right, it is silent, you dont feeel like you are actually rolling the wheel. Furthermore, the back and forward buttons are very far I need to stretch out my finger to reach them I need a moust that is very accurate and has good convenience buttons. What would you recommend me? Money is not an issue.
