AMD athalon XP might be better for you then.
celerons are slow, they cramp up sometimes they'll seem. eh ok, then you do something and it'll think for a few days about.
you just dont want them. you want a pc that will last.
and if you just want them for word processing, one would ask, why even bother spending money on a new one?
i find it hard to believe you woudlnt want to play some games. i mean, as long as your getting a PC, why not make it the most powerful gaming platform in your home? But meh, if it were me, id say your choices would either be AMD or Pentium.
i strongly suggest staying clear away from a celeron
