From my experience linux offers no improvement in general operations or internet browsing.
I would only ever recommend someone use Linux over windows 7 if they did not want to pay for an OS an all they wanted to do was browse the internet. In which case with distros like jolicloud for laptops/netbooks it's excellent considering it's free. Still there is plenty of hardware that just doesn't work with it though, which was one of my major grumbles when running it on a netbook.
Anything more than that has to be windows for me, not really had a lot of use out of MACOS.
