Title: Sleep mode makes this mouse virtually unusable
Review: Everything about this mouse was great. It's built well, feels great in the hand, tracks awesomely, and looks great too. However, beware! This thing goes into a sleep mode after about 5-10 seconds of inactivity and then requires a button click or mouse movement to bring it back. Waking up takes 2 seconds. This is so annoying that it just makes the mouse unusable. You type something on the keyboard, you try to move the mouse, and it sticks for 2 seconds before it moves. In addition, if it sleeps for more than about 15-20 minutes, it goes into such a deep sleep that it is hard to wake back up. It can take 5-10 seconds to wake up. If you think this is quick, sit and wait 10 seconds staring at the computer. I tried to like it but these flaws are fatal. The documentation says it sleeps after 5 minutes of inactivity, but this is simply not true.
