in that case, maybe we should all have given up - trolltech included, and
simply have used windows and visual studio - so we have a consistent os,
programming environment, ui toolkit etc. why should there be any variety or
choice - i mean... qt is a waste of time competing because it's different to
everything else.

variety is a fact of life. UNLIKE other platforms we get the chance to support
all of the variety - at once easily. other platforms force you into their idea
of toolkit, like it or no. at least i dont have to reboot just to run another
app using another toolkit...

and so from that point of view - qtopia would be a loser as it has many fewer
apps written for it than general X11. :)

i never mentioned commercial apps nor money. your idea of open is not mine - or
the next person along's. i prefer the open of mit-x11/bsd, not GPL. all are
free, open and cost $0, but GPL places more restrictions.

if i want to write a library and license it with a less restrictive, yet still
open license, it BECOMES GPL - for all purposes GPL will virally impose itself.
this is not the case if i use gtk, sdl, efl etc., but is the case with qt. it
then would be my choice, as a developer of open, and free software, to choose a
toolkit that doesn't limit my own freedom to license as i please. remember i
never talked about charging for software or it being closed. :)
