Although it is clear that Macs do account for the majority of service requests at your site, they also account for the majority of the machines. You had about .86 service requests per Mac. You had about 1.2 service requests per PC. In other words, Macs at your site are about 48% more reliable than PC's. Also, consider that your IIci's are considerably older than the PC's, so you should expect a few more trouble calls with them. Your numbers clearly confirm the rest of the published data. Macs are considerably more reliable. Shawn -- Shawn V Hernan The University of Pittsburgh Systems and Networks 412-624-6425 svh+@pitt.edu
