You are going to run out of USB ports on your computer. It's inevitable. And sucky! But HP's new Wi-Fi Mobile Mouse helps you conserve those ports by connecting wirelessly—not with Bluetooth, though. Wi-Fi.

This rodent's battery life can last up to nine months before it drains out—supposedly more than twice the lifespan of other Bluetooth mice. You can also stray as far as 30 feet from your monitor and still be able to control it with five customizable buttons, which you can assign shortcuts to (like cut, paste, undo and redo). It'll cost you $50 in June.
