I found a really neat comparison of Mac vs. PC on the itok.net blog (http://www.itok.net/blog).  The comparison is shown below and links to itok.net’s site.

Having “converted” from primarily a Mac user to a PC user I agree with most of the findings in the comparison.  It is still hard to believe with how popular Mac’s seem to be that the market share is still heavily dominated by PCs.
