Windows 7 is not perfect (not saying you said it was), service packs are to be expected even if its only one, think of it this way.
With service packs it is like all the previous updates in one right? Thus the reason SP2 for Vista required SP1, because it didn't have all the updates between SP0 and SP1. Otherwise it would be a 1gb+ Service pack which no one wants.
Service packs in my opinion are not only about fixing problems, but also improving performance beyond that of the original design. Just saying.
