If you just want to do simple tasks then it will be fine. Try and do more than one task and they grind to a halt.IMHO Personally I woundn't touch one with a celeron cpu, I've used a few.
I think this is a much better machine from comet click here. If you buy on line it's down to £479. The 1.7Ghz centino is very good for proccesing power, WiFi and battery life.
