I've been using laptop computers for so many years that it seems odd to need any sort of external peripheral, let alone a mouse that replaces the effective and built-in trackpad on my MacBook Pro. Still, great design is great design and when Logitech sent us one of their tiny matchbox-size Cube mice, I was interested in giving it a whirl, and was pleased to find out that it's far more useful than you'd expect at first glance.
