Computers have reached the same state as cars and household machines, nobody needs a 800hp car, Having 200+ is nice and fun but most people can probably get by with 150 for most daily use. A model from 10 years ago will fulfill the same needs as one from today, the new one might be a bit more efficient, quiet and comfortable but in essence they both just take you from point A to point B in the same time. </inevitable car analogy>
