I'm sure Intel's primary target market are video gamers.

Oh, and I believe the P150 runs 60/30, not 50/25 like the P75.  I
could be wrong, but it makes sense.  P60/90/120/150/180 = all
increments of 30.  If the 90 is 60/30, why wouldn't the P150?  Intel
would be dumb to market a P150 with a 50/25 Mhz bus.  The P133 would
kick its butt consistently in nearly all areas.  Even at 60/30 the
P150 can't be much faster at all than the P133, assuming they are the
same class chip.  Its processor(P150) speed is only 12.8% faster, yet
the bus (assuming 60/30) is 9.1% slower.  Or, the P133 is 11.3% slower
CPU and bus is 10% faster.  Depends which way you look at it.  Either
way, the P150 isn't much faster.
