Prepackaged Goods

Wow, PHP, Apache, MySQL, and other useful stuff all prepackaged and configured for multiple platforms. I love open source.
http://www.apachefriends.org/xampp-en.html was easy to install on XP. I ran an install script and started the server. I installed OSCommerce in 5 minutes! server, database, and shopping cart platform all installed in under 10 minutes. Wow. And with PHP I can take the site back and forth b/w Linux (where my web hosting is) to my machine. And it’s not even written in Java!
