When I converted to Apple computers several years ago they were rock solid... nary a glitch. Not so today...
Not sure if they're as glitchy as a Windows computer since I seldom use a Windows computer but my guess it that it's a dead heat.
Speaking of Windows.... just got back from our rectory as they were having problems with their Windows computer... my GOD but the steps you have to take for even the most simple tasks. I was pulling my hair out. Now some of that, for sure, is that I'm not up on Windows these days... but even when I figured out the steps it was like trying to open one of those chinese puzzles with all the interlocked wood blocks.
