I will disagree on the stabilty. Having used Mac and WIndows, I can tell you that Macs Suffer Kernal Panics almost as often as Windows gets BSODs. I do have to agree with Andrew on the installation (and of the installation of software as well). Ease of use? For the end user, they just have to remember that one task bar is at the bottom (but can be moved to the top) and the other is at the top.
Personally, and I will deny this after this message self destructs, I like Macs better due to the Software and OS installation issues. But Windows pays my bills.
This is true. When I was in the mixed environment, when a DOS user (this was pre 95) called, we asked (always first) have you rebooted. When a Mac user called, we asked, have you rebuilt the desktop?
