I don't think celerons are getting or are considered old. They are really nice and fit perfert into people's budget. They are up to 1.3Ghz I think or that could be the Tualatin, but that and an ASUS TUSL2-c or even a Shuttle AE25 would be really sweet, not to mention that you could use stock cooling and you could give your sister a Pc instead of a lawnmower.
