Keywords: Shorter Laser Lifetime?

While examining specs for CD players, I have observed that Magnavox
samples at 4 times the normal rate, using a single laser.

Many CD players sample at the normal rate, using multiple lasers.

My questions:
   1) Magnavox players are relatively inexpensive.  Is one factor the
       reduced laser count?
   2)  Does the increased sampling rate increase the total time the laser
       is turned-on and thereby reduce laser lifetime?
   3)  Is the notion of sampling faster with a single laser better or worse
       than sampling slower with more lasers?
