The learning curve in making the change is minimal and painless from accounts I have heard.

Macs add all the extra bits you can need -- they drive scanners, they have built-in CD burners and cameras, better quality built in sound, card readers, label printers, external drives, thumb drives, etc. etc.
and, as I pointed out above, today's Macs can boot Windows operating systems, and run all that alleged software natively. But to tell you the truth, I have never been frustrated for want of software in a Mac environment, and often find my applications doing things Intel apps wouldn't do. In any case, it is now a moot point.

Very few who switch from PC to Mac have changed their minds about it.
