Well, if you can detect 'the pinpoint precision and smoothness' or lack thereof on a wireless mouse
at 2000 dpi and above, then you sir, in de wrong wuk. You need to be working by Logitech. Or Razer.
Just how many wireless mice have you used to come to that conclusion? Certainly not more than me.
I use wireless mice because its just plain easier for me, and the latest crop of them could more than
compete with the best wired mice, so the 'pinpoint precision and smoothness' argument has been
rendered moot.
Don't knock it if it don't work for you.
As for the COD thing, its not even related. I haven't played it NEARLY as much (or as long) as you have.
