True - winrar and mirc also come to mind. In today's world of app store DRM at one end and open source options at the other, it's definitely a stand-out more than it would have been a few years ago.
But in this case it also works very well, I think. I know very few people willing to pay $70 for a text editor, but getting to try it out and verify that it's a really good text editor does change things somewhat.
