Yes, Winter is upon us and it sucks.  Even here in SoCal the temp has dropped, albeit just 10 or 15 degrees.   So after hours of sitting at your desk with little to no blood flow, your extremities are sure to get cold.  You can toss a space heater under your desk and before you burn down the office your feet and legs will be warm. But what about your mouse hand, where dexterity is a must?  This standard looking mouse features a built-in hand warmer.  Just flip the switch on the cord and your palm will be toasty warm.
