I saw that...  It is the most interesting offer on the product that I've
seen.  The difference is a good one.  US$ 399.99...  PyQT alone costs
250.00 pounds sterling.  I don't know if I have to have a license of Qt
too or if it is included with PyQT, I'd have to read more carefully to
find it out or ask them that.

This is not my reality, but 250 euros are more money than a lot of
people earn monthly here.  Actually, it is the same amount a worker
should earn in 3 months if he is paid the minimum salary allowed by the
government (actually, there are people that receive as salary less than
1/3 of that minimum...).

So, even though *I* can buy, I still think it is an expensive product.
Another calculation one should do is the ROI of such an investment.  So
far, as I said in my previous message, the demand for it has not
convinced me to buy it.  Yet.  And yes, I point it out as an option in
some projects.

If PyGUI will have native widgets for Windows as it does for Mac, I hope
it becomes standard.  Its API seemed cleaner than wxPython's (and with
one less emulation layer than wax, as pointed out on this thread...). 

With regards to charging, one must take into account the economic
reality of the place where such a person lives.  If you see the above
you'll see that the cost is not the only problem, the value is (there's
a difference in being expensive and having a high price... at least in
Portuguese there's an important difference).

This is what led me to use wxPython on one project of mine...  Even it
being free software, I need to keep a Windows version of it for another
year or so.

Dell is with low prices here, compared to what we see on the market.  I
was looking at one receipt two days ago, with another consultant, and we
saw that a 1600 with nice hardware cost near US$ 1300.00 here.  Buying
the same machine -- P4 2.80 GHz with HT, 80 GB SCSI disks capable of 80
MB/s at 160 MHz, 256 MiB of RAM, CD, Gigabit Ethernet adapter,
etc. etc. etc. -- anywhere else would be more expensive than that.

I remember iBooks starting at something like US$ 2100.00...  That's more
than half of the Dell :-)

I wish we had those prices here...

Indeed.  But then, if you bought the other computer without Windows and
added a free operating system -- you said you use Linux... --, with its
development tools, then things would start being more comparable.

*sigh*

I've read somewhere about enhancements to this function in the most
recent kernel.  I can't say anything about it, though, since I don't own
a notebook.

Heh.  I do something on the same line you do: cheap boxes with a good
OpenSource OS where they fit.  And I also need a good box with a good
OpenSource OS to me. ;-) 


My machines here are 100% free and in the country where 60+% of the
software is illegal, I'm very proud of saying that there's nothing
without a proper license here :-)


Maybe I'm just talking about BlackAdder's/Qt's price because of this
culture here or because I'm used to use free (as in free speech and in
free beer ;-)) software...  But I really think that if it was cheaper it
would be more used.  I have bought several software for my PDAs, some
for my old mobile too...  

If I had to pay something like 5 dollars for each copy of the software
or something more expensive for a customized software (e.g. US$ 50.00,
if I sell the product for less than US$ 10,000.00 and more than US$
1,000.00, US$ 500.00 if US$ 10,000.00 < my software price < US$
100,000.00, etc.) it would be more interesting from a commercial point
of view and would also be easier to include such a cost at the product
price.

Of course, I'm looking at my side, they found that their business model
is different and I must either accept it or not use it.  For now, not
using it -- even liking more the appearance of the widgets -- has been
my choice.



I guess I deviated a lot from the original intention of the post, and
I'm sorry for that.  It wasn't my intention.  I just wanted to see the
toolkit on the OSs it supports :-)



Be seeing you,
