Not only did flame avoid looking at the site, but he's also missed out on the Windows port of The GIMP, which was originally a Linux photo-editing app. It's just as powerful (if not moreso) than Photoshop, and is free.
He's also probably missed out on OpenOffice, which yet again is arguably so much better than MS Office, and approximately $399.99 cheaper (price according to MS online shop). In other words, also free.
Pretty much every app that's been ported from Linux is avaliable open-source.
