WAMP vs XAMPP pros/cons – for running a local testing server

XAMPP is NOT cross-platform. There is XAMPP for Windows, XAMPP for Linux, for Mac and for Solaris, but each pack contains different pieces of software, runs differently with different performance, etc. (cross-platform means that you take the exact same piece of software and it runs the same way on different platforms … like Azureus used to be: a jar that you could use the same way)
