What does that get you? Why is running Linux for email/web + Windows for
the apps you use to get your work done better than running Windows for
email/web/apps you use to get work done? If you run Windows in a VM you
still have to maintain it, keep it up to date, free of viruses and make
sure it can log onto the network so random-business-app can read your
$HOME etc, so you're effectively maintaining two computers
instead of one.

Depends on the type of app. For retail apps like Photoshop yep of course I
want to see native versions. There are advantages to doing this. Of
course, native and free-speech software is even better. For random custom
VB apps and the like yeah, I think Wine is the long term solution. It's
really a matter of philosophy.
What does making an app native (or a portable web app) get you? Well ...
it makes it integrate better with the host environment, uses native file
pickers and themes etc. Wine has some basic theming support, maybe one day
it'll be complete, but still native apps will usually integrate better.
It means you're less likely to hit tricky bottlenecks or hard to map
features. Native libraries are wider used so more likely to be bug free.
What else? A bit faster, I guess, though subjectively I can't tell the
difference between Wine apps and GTK2 apps these days, except in a few
pathological cases. Word still starts in a few seconds relative to ~30 for
OpenOffice, so Wine doesn't mean slow. IE still starts and renders pages
as fast as Firefox, to my eye.
So there are advantages. Where the ratio of developers:users is really
huge, like for retail software, it makes sense. You can get a leg-up in
the marketplace by giving your app that extra polish implied by going
But most software isn't sold on shop shelves. Are these advantages so
great that they justify humanity collectively rewriting thousands of
man-years of work to use the API du-jour? Is this a useful way for the
human race to spend its time? Or should we simply continue to run legacy
apps like we always did, and write new software to use newer/better/more
free APIs, maybe migrating old apps slowly over time, as it makes sense to
Well, this position is definitely arguable, but I'd say the latter. I
can't think of a single compelling reason why everybody should rewrite
*all* their software. It just doesn't make economic nor social sense. We
could be spending that time writing *better* software that actually moves
society forward in some meaningful way, rather than simply changing
CreateWindowEx() -> gtk_window_new() which for the effort expended
achieves very little.

Heh. I'd be happy for them to support free software as a Windows migration
path. Even if they decide to compete with CodeWeavers (unlikely), I
haven't noticed the presence of SuSE or IBM in the market hurting Red Hat
any. Currently the RH "What do we do about Windows?" strategy seems to
involve hand-waving, web apps and VMware.
This isn't surprising, RH have always been a Linux company so they have
little experience with large desktop migrations, entrenched users,
unwilling 3rd party vendors etc. Novell are getting this experience
now. I'd *love* for RH management to give their backing to the Wine
project, but I suspect they'll first spend some years nicely asking
vendors to rewrite their software as web apps, or nicely asking existing
web app vendors to please not depend on ActiveX/IE specific DHTML/ASP etc.
Unfortunately, some apps will probably never even be ported. Why?
Sometimes it's because it's not economically viable, sometimes the source
code has been lost (this is more common than you might think!), sometimes
it's so heavily dependent upon Windows APIs a port would imply starting
from scratch (see Open Workbench for an example), and sometimes it's
simply been abandoned by its creators: the shelf-life of a game for
instance before the developers stop caring about it is about 6-12 months.
After that time is up they're unlikely to even patch it, let alone do
ports. Oh yes, and some of it is made by Microsoft, see eg BizTalk or MS
Project which have no native (free or non-free) equivalents.
I'm sure lots of programs will become web apps or be ported to native
APIs in future. But saying it *all* will just makes me realise how little
experience our community has with large-scale desktop migrations.
