Because SCSI drives are much more expensive counted in dollars/megabyte
than ATA drives.  The performance-gap between SCSI and IDE has also
decreased quite a bit in recent years.  
A significant part of the performance advantage of SCSI over IDE is
also simply because SCSI drives tend to have higher rotation speeds
(10000 rpm or 15000 rpm compared to 7200 rpm for a typical IDE drive
today.) The higher rpm means more noise and heat from the disk, making
it less suitable for desktop machines.  

It is also worth noting that for the typical access patterns of
single-user desktop machines the performance advantage of SCSI is quite
small, and generally not worth the higher cost.  It is for busy
multi-user servers that SCSI really shines, which is a relatively small
market.
