As I said, I am not an expert, but when you say "programs", what kind of
programs are you referring to? Everything that happens to be included in a
distribution (for example Emacs, OpenOffice.org, GIMP, Ardour, Inkscape and
VLC) or only those you absolutely need to be able to do or control something
(for example System watch, Synaptic and Networḱ configuration)?
Personally I don't consider Media Player and Internet Explorer as a part of
Windows, even though they are included with the operating system by default.
So if I am not happy with some behaviour of a certain program I will look
for an alternative and/or let the developers know what my opinions are. For
example (lots of examples here…), when I found that Nautilus, after being
updated, suddenly started to add "Link to " to link names when creating a
link by using the mouse, I filed a bug report about it (actually I didn't,
because there already was one, but I added my comments and workarounds to
it) and I looked for another program. Unfortunately I didn't found one that
I liked, but at least I tried.
