> I understand the controversy with the charging port being under the mouse, but it's done on purpose: Apple wants to prevent users from leaving the mouse connected with a USB cable all the time.

Here's a better solution: good old rechargeable AA batteries. Keep a spare set sitting in a charger, and you'll never need to wait for your device to recharge.

If you're concerned about users falling back on disposables, bundle two sets of rechargeable AA's and a charger. Apple used to sell branded versions of these items.

I hate built-in rechargeable batteries for peripherals like mice, keyboards, and game controllers.
