Keep in mind that during the days of pre-xp, when they announced the system requirments, everyone was going apeshit. they seemed ridiculous at the time, but seem like nothing now.
it is all about leaving head room, letting the technology grow to fit the shoe.
this type of design also creates better business for everyone... when xp came out, companies and enduser's alike were rushing to finally *upgrade* their systems. due to supply and demand, prices decreased, while speed and size of componenents increased; bigger hard drives, faster processors and ram, better video cards to support the eye candy.
it is the software that sets the standards for hardware these days; games, programs, and operating systems, not the other way around.
