The age old argument of "I spent all my time learning it THIS way, and this other program wants to do it THAT way. It sucks because it's different!"
I find it funny that when Pagestream was released for Linux, guess what style interface it used? That's right, the one that Gimp uses. With a separate toolbox from the main window. It's perfect for dual screens.
I realized the other day, when trying to use Dia or Flow to create some network diagrams, that I just don't use Applications anymore... weird, I know... I'm a Linux system administrator by profession, and I can get things done faster by the command line. Graphical user interfaces are starting to annoy me. Maybe it's because when I come home, I play around on my Amiga, and love how it's set up. Only thing I use Windows for anymore is when I'm in the mood to play an (eye-candy) game. A good chunk of those are coming to Linux, so that'll eliminate that need.
But overall, the majority of graphical applications I do end up using are Evolution (email) and web browsing. I could probably use Mutt instead of Evolution, too bad the Web is so graphical these days... or I'd ditch that too!
But as this thread is about the benefits or the want to open source Amiga, the whole "this open source application's UI sucks!" isn't even remotely on topic.
The Amiga, much like most other graphical interfaces, have guidelines for 'proper' application interfaces. Much like Gnome and KDE, etc on the Linux side and on the Windows and Mac side. But they are just guidelines.
I've found every 3D rendering software I've ever played with to be annoying, except perhaps Maya, which was way cool, but I really don't have the talent to use them. But I also won't go into forums and rant about how much they suck. I have ranted back at people who put the hate on the Gimp, simply because it's all open source, if you have such a vicious hatred toward it, FIX IT. The GPL even would let you fork it and call it GIMPSucks if you so wanted to. You would probably piss off a lot of people, but then so do politicians
