I like how they mention keyboard manufacturers using the term up to as a way to deceive customers, and then in the next paragraph mention the same phrase when referring to the Microsoft keyboard.

'Another marketing strategy is to state that the keyboard allows "up to" some large number of key presses.'

'Microsoft's SideWinder X4 features multitouch technology that allows it to detect, and report ANY combination of QWERTY keys, up to 17 keys.'
