Specifically the new laptop series mice - 4000, 6000 (laser).

I would like to know how good the range is on it, because I bought a 4000 model for my sister for Christmas for her desktop. I got this over a standard desktop mouse because it uses a mini receiver and you wont have this big clonkin receiver with a cord sitting on your floor. So I want to know if this should be alright, because i know MS mice isnt quite as good as Logitech when it comes to mice range. Or even if any of you guys use/have used wireless notebook MS mice on desktops, please feel me in on how you found it.
