Being a BeOS user (a purely desktop system) and because I code under Linux, I see
XFree86 (v4.1 on my machine) as a user and as a developper. And this is where the problem lies. My Gnome or KDE desktops are slow in comparison with other operating systems, but XFree86, the 'engine' behind these desktops, proves me that it's not. Let's look at what I have in front of me: a dual Pentium III at 933Mhz with 512MB of memory, a Radeon 32 AIW, a modified Mandrake 8.0 powered by kernel 2.4.18.
I liked this article. I think that reinventing the wheel is stupid. X always was used in high-performance graphic workstations like SGI with Irix.
The only problem with XFree (a particular implementation of X) is imaturity of drivers and lack of tweaks like the autor suggested.
B.E.OS for me is the only BeOS clone that will have a chance to not be only another geek toy. Using the popular linux kernel and XFree will assure that it will have many device drivers. Sorry, but the original BeOS will die because it will not have drivers for future hardware.
XFree project could make a easy "driver kit" and donate to video adapter makers, to incentivate certified drivers.
