More or less the same reasons as you; I too think it's a
great product, but...
Recently, I was to program some GUI stuff in Windows, and I
have no knowledge of Windows programming whatsoever. So I
tried to use the tools I know: Perl and Tk [outside of
Cygwin. Maybe I should actually have tried that??]. It works
fine enough, until you try to do something a little specific
(in my case, bringing serial port events in the MainLoop
killed the project) and then you suddenly realise where you
live: pipes don't really work, select only works on sockets,
serial port handles must be held by only one process...
And that's when I realised that Windows and Unix have
fundamentally different programming models (well I kinda
knew that already) and trying one model on the other
platform tends to be asking for trouble, or at least dire
All those years ago, I convinced (easily) my management it
was easier to do Embedded Linux development on native Linux
machines. This time I managed to convince (less easily) the
factory that they're better off with a Linux app, and that
it's really not that hard to use.
The day Windows is really really *really* required, I think
I'll be better off learning proper VC++ and actually program
Windows as it was intended (even if I actually disagree with
most of it :-) ). Or more likely, try to dump that project
on someone who knows Windows already :).

Yeah, Windows isn't good at creating new processes (and
having an antivirus open makes it *much* *much* worse).
That's part of the fundamental differences: Windows makes
massive use of threads within one process, and rarely
creates processes. (For the interested: the other big
difference is a massive reliance on callbacks. I strongly
suspect that has to do with Microsoft's GUI background,
which they applied to everything. Incidently, that may make
Windows' API better suited for real time, but that's another
Marbles should be kept together.
