Definitely, having the kernel support the GUI features is bad idea IMHO.
but, What X lacks is a _standard_ toolkit, _complete_ widgetset for developers.
We have
acrobat using Motif distributed along with the reader, xfig "needing"
preinstalled Motif, Xaw using Athena, Gnome apps using gtk, KDE apps using
QT... and so on. Moreover, there is no standard interface for
communication between these apps using myriad toolkits. And all of this is
a duplication of effort that can be totally avoided.
As an app programmer, one is always faced with the question, "which
toolkit do I use?". And there is never an easy answer. I guess its high
time for ppl to realize this. If any thing, this is definitely one thing
thats slowing down the acceptance of Linux as a Desktop OS.
