the geforce go 7600 graphics are better than integrated graphics. but since you don't plan on playing any games, you won't see any real benefit from it. you could find a core2duo based laptop for the same price but it will probably have a 1.6ghz cpu and won't be any faster.
similar gateway laptop for $769

unfortunately, you'll have to toss one of your ram sticks to expand. so $80 for a 1gb stick will only result in 1.5gb of ram.
