I had enough of this Microsoft Optical Wireless Mouse 2.0, it works when it feels like working and even then I get a delayed reaction once in a while. It makes for a very unsatisfying experience and using the trackpad for extended periods of time is not the most productive approach either. So, if you are using a great wireless mouse that would work well with a laptop please let me know. I am researching more about this one in case you already own it.
