If you've been waiting oh-so-patiently for HP's $49.99 WiFi Mobile Mouse to ship, take heart -- the aforesaid critter is now ready to free up one more valuable USB port at your workstation. As mentioned before, this ain't your mum's wireless mouse, as it makes use of WiFi technology -- you know, instead of the tried-and-true Bluetooth. In other words, this bad boy doesn't require anything other than itself to connect. HP promises up to nine months of battery life, offers five programmable buttons, a four-way tilt scroll wheel and adjustable sensitivity. Just think -- you can finally choose to keep those remaining Four Loko cans chilled without resorting to an inbuilt trackpad. Reason enough to pull the trigger, yeah?
