Pros: Made an immediate impact on my game play. I orginally picked one up at Best Buy. I put my hand on the display model... it was like Arthur pulling the friggen sword from the stone. Light weight which I prefer (even lighter than the G-5 with no weights). With up to 1600 DPI you can adjust to your comfort level on any game/ap. 8 programmable buttons (2 of which are assigned for on the fly DPI adjust) including 2 thumb buttons (screw the pinky I say!). Sleek black and charcoal look... smooth top helps keep hand relaxed for hours of play.

Cons: Ok... I've had it like 10-11 months... and the left mouse button is starting to flake on me. But consider... I am a heavy gamer... both from home and various LAN parties (meaning it gets carted to other locations with the rest of my gear)... I also work from home quite often (usually between 10-20 hours a week... more if the boss is out of the office too ;). In the end... I like the thing well enough to buy another one without much debate. I hope they never stop making it! ... as someone mentioned... it does get dirty... but I don't think more than any other mouse... its just the smooth gloss shows the dirt more. Probably shouldn't be playing with greasy fingers any way ;p

Overall Review: Does it bother anyone that "think outside the box" is a cliche and therefore pretty much an ironic statement?
