This is an interesting thread to me. I think I understand some of it, and am concerned and confused about the issue of too much complexity invading linux. When I first saw the thread I wondered if the latest greatest OpenGL desktops were suspect. On opensuse I can configure the KDE desktop to use different versions of OpenGL "rendering," or I can choose Xrender. I just have an Intel motherboard GPU, so linux has it covered. On older opensuse distros the Xrender desktop is noticeably different. Maybe it is a good idea to dump all the graphics work to giant new video cards. And maybe the old guys doing console command line linux are smart. But maybe simple X11 or whatever it's called today worked pretty well, too (for the rest of us bumpkins). Same concern for going from 32bit to 64bit. In the linux quest to be a great choice for every user platform, they might compromise quality. At my age, I can live with opensuse 32bit and play with my PCI serial ports using X11 until I enter assisted living. If I have a rationale it would be that industrial automation ain't gonna screw around with iPads and WiFi and 6 channel music. Great post, great conclusion. Thanks.
