Query: good tb

I'd like to echo the complaints about installation. I'm an experienced user/tech and the space to activate the acceptance is new to me also. The response I get with this is excellent through the pS/2 port and it has a good feel. I am partial to trackballs though. Some just can't adapt. My only nitpick is that the scroll wheel is a little to notchy for my taste. Good remote pickup also.
