I created my “hackintosh” a few weeks ago on my Dell Dimension 9200.  The main reason was so I could check out TextMate - the editor most Rails guys seem to use.  I’ve been using NetBeans on Ubuntu for a while now and like it, but just wanted to give TextMate a whirl.  Well, after using OS X, I’m really starting to dig it.  Not sure if I like it as much as Ubuntu, but it’s better than Windows.  Some things take getting use it - like the close/minimize/maximize buttons on the left side instead of the right.  Also the application menu always betting at the top of the screen is strange, although in some ways nice. Oh, and TextMate is great.
