Well, they may *run* technically, but I think that most of us will agree, 
Quake III plays better on that Athlon 64 than it does on a 486.

You can hide the hardware from the programmer, but you can't hide its 
performance from the user.

If a later generation of the $100 laptop comes into circulation, you'll see a 
lot of annoyed people when their friends get one of the new ones and it runs 
the tasks which strain theirs more easily.  And even more annoyed people when 
people start coding assuming that level of performance is available.

Yes, hard-coded delay loops and other similar thinking is bad.  But it 
doesn't prevent it from happening.  It will always be tempting to do it that way 
too, if you have fixed hardware.  It's easier.
