Greetings from Kyoto (home of the protocol)...
Good news indeed, I used KDE (Mandrake/Mandriva) almost exclusively
from 1999 to 2005, then I changed to Ubuntu and Gnome.
I found that at the time of my change to Gnome in 2005 I found that
was a more stable platform than KDE but lacked the features of KDE.
The opposite was true in 1999 and thus the reason I used Mandrake/KDE
rather than Redhat/Gnome back then, although that might have been
because Gnome was usually paired with Enlightenment back then.
Recently I also played with Kubuntu (8.10) and came across the same
bug (?) that annoyed me with some Mandrake/Mandriva versions, that
after you run a software upgrade all of the fonts change and it almost
impossible to get them back. What made it worse in Kubuntu is chosen
tiny sizes which are almost unreadable and even going into the font
section and setting everything large still hasn't fixed all of it and
in other places made things too big!
Anyway the good point about QT is it C++ based so much easier to
integrate into applications than the C based GTK. Changing from GPL
(and others) to LGPL means than any software you write using the QT
library no longer has to be GPL itself, which will see more commercial
use of QT?
Although the bad point is the lack of competition between the
different desktops, but that may be a good thing in terms of pushing
Linux forward to the masses.
Just my little rant...
