You'd be surprised how noticeable a few pounds are, especially when you travel frequently. I work out and can lift a lot of weight but would (and did) pay extra for a thinner, lighter laptop all other things equal. Thickness can also make a big difference when trying to work in tight spaces (eg an airplane) or packing a carry on bag.
