Same reason my household is on that combo (but with 10spd deraileurs). Already had 10spd. But with regards to "upgrading", we certainly can't be arsed to drop $250 or more on a replacement cassette and chain, when a desirable spread exists for around half that. That money goes toward other fun stuff.
