The mouse will be recognized under the standard operating system (Xandros) the EeePC immediately. A driver installation is required (of course, you then can not use several keys, but that should not be necessary). The changeover stepless / gradual Scrolling is also possible without drivers. The mini-mini-mini-stick falls on EeePC hardly; the EeePC then still fits with inserted flash drive in his pocket. Super: The Off button on the mouse saves power because the EeePC is not always in operation. The mouse is great in the hand. Very nice mouse bag included. Recommendation: Buy!
