yeah i'm not constantly using the mouse for games so that would be why! 
as for the keyboard feel - i rate it as the best i've ever owned. i had mine since it came out about 6 months ago and my roomate just bought one last week. they both feel the same and mine deosn't seem to have worn out at all. try it at the store before you buy or get it from a store that will allow a return if you don't like it - they're $99 from a lot of places now.
also, the main difference i notice is that the connection doesn't drop anymore. it used to be that if my cell phone rang there would be a lag while the keyboard tried to set back up to the base but that hasn't happened since i got the new one.
