After umpteen years as a PC user I took the plunge and bought a 24" iMac. Loving it so far!!! I can't totally abandon Bill Gates because I do Windows software development for a living and my company also relies heavily on MS Office for proposal and tech writing. I tried handling some of our more complex documents in both MS Office 2008 for Mac and iWork Pages, but both were less than 100% compatible in handling some of the more complex document features. So the first thing I did out of the box was load up VMWare Fusion and create an MS XP virtual machine. XP in 512MB of RAM in a virtual machine on iMac is actually running as good as or better than XP natively on most other boxes I've ever seen. Got all of my MS Office, Visual Studio and database tools right there when I need them, but otherwise am happy as clam to be exploring the wonderful world of Mac. As happy as I am with the purchase, I did almost immediately disprove the notion that Mac OS "never crashes". I downloaded the trail version of iWork and as soon as I tried to view one of the video tutorials the entire system froze up at a blank gray screen. Then to my utter panic would not restart, even with a hard power reset. But the boot up failure looked eeirly similar to a "no OS partition" response you'd typically see on a Windows box. On a whim, I pulled the plug on a USB hard drive that I had attached to transfer files over from my PC and did another restart and sure enough, it came right up. So it seems as if the Mac was possibly trying to boot off of the USB drive. I'm still learning the Mac way of doing business but so far I think this is going to be a wonderful experience.
