Often buys (me, anyway ...) to find an external keyboard on a laptop the comfort of a full keyboard. This product enables the opposite: to place, on a landline, a keyboard without the numeric keypad but with touchpad. Pure masochism? Not necessarily. The most obvious benefit is probably the use of a machine from a sofa rather than from an office but this device is also very suitable for posts having a reduced work surface, especially if it is often be freed to do other things. The fact of not having a mouse simplifies maneuvering and then, as long as you are not allergic to touchpads, this choice can be very wise.
