That comes in a combo with the wireless wave combo so that is tempting..I've a Logitech M510 and have been very happy with it, it's nothing overly fancy but it feels good and is accurate.
The G700 is my favorite mouse of all time. And I've owned quite a few different makes and brands. I'm also kind of a latency whore and IMO it's more responsive than a wireless 360 pad. So it's very responsive. Never thought I'd switch to a wireless mouse after some earlier experiments, but the thing is quick.
Has awesome drivers (not something you usually associate with Logitech). Only thing is, the one Eneloop rechargable battery it comes with doesn't last the longest. But as long as you have 4 spares lying around and a 4 battery charger, the thing is absolutely perfect (price aside... but I got in on sale at amazon for 49.99).
G700 was definitely one I was thinking about. I'm cool with having multiple eneloops around. Thanks for your insight. If I see a deal I might jump on it but the current price is a little high even though I'd use it a lot.
