I'm one of those IT guys who want to get rid of his Macs, and it's not b/c of fear of losing my job. It's b/c Macs make up 15% of my machines and 50% of my service calls. It's b/c I've had to replace a row of memory on a year old Xserve twice while two racks of HP and Dell servers chug along, "just working". It's b/c I spend so much time at forums like these learning and applying all the tips you mentioned to my G5's and I still have $800 HP's that run Photoshop and Illustrator just as well as they do. Not to mention how whenever we plan a project/upgrade, we have to spend a lot of extra time getting the Macs to work with whatever we are doing. I just tested out a great Internet monitoring device. The techs who came in were both big Mac guys with their Macbooks. The device was incredible, except that the Macs wouldn't work with it. They never could get the Macs to work so we had to scrap it, but that didn't stop the two them from constantly making "baseless, idiotic compalints" about my pc's and Vista, even though all of those machines worked perfectly. So, scared I'm going to lose my job b/c of Macs, no. Want to quit my job b/c of Macs, yes.
