i recently was given an old dell latitude CPx. it has a pentium 3 processor, 128mb of ram, and a 7.44gb hardrive with about 700mb free! the stickers on it say it was designed for windows nt/98, somehow it's running xp but very slowly. What alternate operating can i install that will run quickly? i was thinking an older edition of ubuntu? the laptop will mainly be used for internet and possibly downloads via an external hardrive although this is not essential. any ideas?
