Being a cross platform (more than one computer with different operating system platform) user, I am quite familiar with both Macs and PCs.
I can tell you honestly, although there are some unique differences, they are no so different, that a long time PC user cannot not adapt to using Macs and even work with both in a mixed network environment.
In fact it is quite exciting the increasing flexibility there is to use select files, photos, music, video and more between these two platforms.
If I may inquire, what products are you specifically looking at in terms of Macs?
