You are going to run out of USB ports on your computer. It's inevitable, and can get pretty annoying when it happens! But HP's new Wi-Fi Mobile Mouse helps you conserve those ports. It connects wirelessly - not with Bluetooth, but with Wi-Fi.
This rodent's battery life can last up to nine months before it drains out - apparently, that's more than twice the lifespan of other Bluetooth mice. You can also stray as far as 9m from your monitor and still be able to control it with five customisable buttons, which you can assign shortcuts to (like cut, paste, undo and redo). It'll cost you $US50 in June.
