I owned an N80, held an N90s but declined to buy. If I still had my Nikon kit the N80 would be seeing a lot of use. Very nice camera. Can't say anything at all about the N90s, other than it was a semi-pro model, and is several years older older. The N80 was very responsive, light, and very quiet. If you need speed, get an F5. Otherwise, get both, the functional differences between them are marginal at best.
