Why the Hell wasting time turning ATA/ATAPI into another SCSI thingy, but different ?

If SCSI was sold like IDE drives are, they'd get cheaper too... I must miss something. There was a time where SCSI was for high-end systems and IDE for smaller ones. Life was simple. Now they're turning IDE into SCSI. WHY ? -- Ollivier ROBERT -=- FreeBSD: There are no limits -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 3.0-CURRENT #29: Tue Aug 26 21:05:09 CEST 1997
