I don't notice a difference with surfing, that's more of a browser issue and the most common ones work on both. I can still use iTunes and the iPod, viruses are more common, I'm still not used to the user unfriendly file system on Windows.
I'm not familiar with Safari, I left the Mac environment about 5 years ago when it was stolen in a break-in. That was a blessing in disguise, it was an ancient Mac IIsi and I got the full price I paid from insurance - over three thousand bucks for an obsolete machine.
