[Qt-interest] VS 2010?

As far as I understand, commercial does not guarantee all supported
binaries are built for you.
It has never been this way. Not even when Trolltech owned Qt.

You used to need commercial version just to use Qt in commercial product.

The only point of having commercial version these days is to be able to
change Qt source (any modifications to make it run on specific platform or bug fixes) without
reporting the bugs/request changes and wait until the official version is updated.

I used to think like this. After a while I ended up having to build Qt from
source anyway, because its the only way to incorporate patches from Qt
support. Since I have never used a version of Qt that hasn't needed patching
to be shippable with my product I think it's safe to say you need to get
used to building from source.

This is a shame, because I like the idea of using binaries that have been
properly QAed by the trolls rather than built on my machine using some
random configuration. But I don't think there's any way around this given
the current policies about what goes into the minor updates.

As for the point of the commercial version, for me the main benefit is fast
turnaround on support questions and bug fixes/workarounds. Also I would like
to think being a commercial customer makes me somehow important to Qt but I
really doubt that these days...

I know, same here. I try to do it overnight.

Can't you automate all this and farm it out to EC2 or something? If someone
offered a service to build custom Qt builds remotely I would consider using
it too.

Based on what Thiago has said in the past about their patching policies I
concluded long ago that official binaries were provided as a convenience
only and that the binaries are not considered part of the value proposition
of owning commercial Qt licences. I agree with you that it would be nice if
it was otherwise but I think Qt would also need to commit to better bug-fix
policies on the commercial releases for this to be usable.
