Do a search on the MX1000 here and on the Logitech forums and you'll find that people who love the MX1000 aren't bothered by the reaction time lag of the mouse that occurs once you remove it from a surface and then replace it on a surface. I'm one of those gamers who lifts the mouse a lot, so the MX1000 was a nightmare for me. I quickly switched back to the MX700 and see no reason for switching to anything else anytime soon.
