In 1 word. Weight. Logitech has already solve the problem with cordless lag, but they still haven't inventented weightless batteries. The weight of the battery in the cordless mouse can be annoying to some and downright handicapping to others. As for me? I use MX700 to play FPS, which is very mouse orientated game. I can get used to the weight of the mouse by increasing the acceleration and speed of the mouse. However, some people just doesn't feel "right" with a heavier mouse.
Personally, here's my pro/con of my MX700:
Pro - Added weight gives me extra precision. The extra weight allows me to have sturdier aim and more accurate small movements. Best used as sniper or long-range shoot out.
Con - Added weight degrades my ability to react quickly. Even with tweaks in the setting, the weight decreases my reaction speed.
