You know that pseudo-tactile feeling you get when you fondle your mouse's clicky scroll wheel, the one that satisfies your obsessive need to touch everything? Logitech wants to give you more clicks, and smoother scrolling to boot. This M325 wireless mouse's new "micro-precise" scroll wheel features 72 tiny ratchets, making our self-counted 22-ratchet mouse wheel seem downright barbaric by comparison -- not that we ever really considered the number of teeth our mice had before now. The rodent's 18-month battery life won't quite live up to your 2-year Couch Mouse, but at least they can share a Logitech Unifying Receiver. Your scroll wheel of tomorrow can be had for $40 later this month, or £30 right now for lucky folks in the UK.
