I have one on my desk. It's the biggest non-issue ever. Do you ever need to go to the bathroom? Or get up and get a drink of water? Plug it in, and by the time you come back, you have enough charge to last you the rest of the day. Remember to plug it in overnight, and you've got at least a month of charge. It's just a ridiculous complaint that it can't be used while plugged in. It's a wireless mouse - why would you want it to have a wire?
