Hi, For me, Windows is not even remotely comparable to OS X for a software development machine. These are some very useful tools for software development that come with OS X. Straight out of the box.

In my experience IDEs like Eclipse, Flex Builder, Netbeans etc etc work fine on OS X. Basically, OS X is a /great/ developer platform. cheers, - shaun
