Another thing-- and I guess this is what's meant by more "user-friendly"
I'm going to make a stupid metaphor. Imagine that the two different OS are bridges to wherever.
The Mac has guardrails; the Windows doesn't. You may say "only autistic newcigarettes will fall off the bridge, that's why Macs have them" but that's not true.
For example: rather than it all coming down as a list, to put the computer to sleep in Windows 7, you click on the arrow next to Restart and then some more options appear. If you move the mouse ONE LITTLE bit less, it will suddenly restart without asking for confirmation, closing all your windows and logging out without even seeing if you're sure.
There are so many LITTLE things like that that just make Windows worse to use.
