Mono does give you the portability; slapping on a different GUI layer
to be able to sell your product into those markets is a must as a
business case for me; but feel free to disagree. What I'm saying
about writing with different user interfaces in line is abstracting
your core logic from your presentation layer. There are numerous
benefits to this aside from just supporting in our specific

I agree with you on the attraction/sexyness of mono wholeheartedly
otherwise I would be doing none of this work in my spare time.

Here is where we start to disagree; Gtk2.10 can "gain" a quartz
driver from Cairo which is great; its still missing the entire
windowing system (please see how the cairo quartz driver works) so
the quartz driver != instant gtk on mac. In my opinion (and I am in
"IT Management") this really is pointless anyways. If you want a
fully cross-platform UI; deploy a web app. If you're writing a
desktop app that you expect windows/mac/linux people to all be able
to consume; you damn well better have a fully native experience. Mac
users are the worst and most notorious for this. Hastily ported
windows apps that dont feel "mac-ish" die on the vine and have little
to no sales into the mac community.

I'm back to agreeing with you here in some senses. I think Mono
provides a fantastic cross-platform solution (today) for middleware
and backend. I still firmly stand by my belief that there is no way
to write a completely cross-platform GUI toolkit that will address
the needs of the 3 major audiences. (Alt-F4 on windows maps to what
on Mac? Mac users hit Apple-Q for a nitpicky example, yes we could
map that one; but where does this stop).

I'm always open to suggestions / constructive criticism :)

I can't speak for the entire mono project; but the long term road map
for Cocoa# is to evolve it into a more "first-class" citizen on par
with Gtk#. A number of the changes I've instated in it map the Apple-
esque API to a much more ".NET-esque" API (think EventHandlers;
instead of action/target selector/object pairs). This should ease
the road of moving a presentation layer to it. I frankly see Cocoa#
as the solution for windows/linux devs to get onto the mac; and
objectiveC# as the solution for mac devs to leverage the CLR. Toss
in a mix of continuing to make sure everything works well on PowerPC
OSX for the next few years; and X86 osx going forward as well and you
have my roadmap :)
