If you want to develop in C++ as well, you need a Qt license.  What you
get with BlackAdder comes with a license to redistribute only apps you
write in Python, not those you write in C++.

That's the key one, of course.

But if the customer buys it, rather than you, the ROI is going to be
lower.  They get a license to redistrib apps they won't ever write, and
you're back to the same issue on the next proj for another customer.  If
you buy the license, you can then redistrib to any or all of the many
customers you write apps for.

Yes.  It all depends on somebody wanting to scratch that particular
itch, as usual for opensource projects.

iBooks start at about HALF what you remember.

I wish we had those prices here, too.  We don't, so I buy in the US: any
AppleStore there is happy to sell me an iBook, and Apple's warranty on
portable products is worldwide.  (And I far _prefer_  the US-layout
keyboard I get that way to an Italian-layout one -- US and Spanish are
the only layouts you can buy in the US).

Why Apple chooses to price stuff cheap in richer countries, US foremost,
and dearer the poorer the country, I dunno.

Indeed, Linux is what I run on desktops, and I go back with it to 0.92.
But on laptops all of my attempts haven't yet produced one that can deal
with 'sleep' properly, while on the iBook _it just works_, no hassles.

I'll check it out eventually, since I do have a couple of old
intel-based notebooks.  But I've heard about such enhancements about
every release on the last few years so I'm not holding my breath.

That's very important -- piracy is pretty widespread in Southern Europe,
too, and from my POV what it does is first and foremost present unfair
competition to free software.

Hmmm, but it seems that the main issue you have with Qt is that it's
free only if you DO use it on and for free software -- that's what the
GPL is all about.  If a free-software culture it's OK; in a
software=for=money culture it's OK; it seems to grate only on developers
who want not to pay for the software they use but still charge for the
software they sell.

Personally, I'm extremely happy that the culture of commercial software
is moving away from such complicated pricing schemes that were the norm
some years ago.  The attempt to reflect "what is this sw actually worth
to YOU" doesn't work, anyway.  I can have a 1000-$ program where, say,
Qt's functionality is actually 80% of what I'm doing -- a program that's
mostly-GUI... -- and I can have a 10000-$ one where the GUI matters very
marginally, say the program is mostly about clever heuristic engines
scavenging through DBs and networks and all I want is a little sysadm
GUI console on the side for a customer's sysadm to keep an eye on
things.

It's definitely your choice.  I do hope you get some opportunity to do
GPL development and try it out, because I think it's really good.

If you're looking for a native appearance on Windows, as I understand
things, you won't get it with PyGUI until somebody makes a back-end...
