I would disagree with the above quite strongly. We have an application
which runs on more than 20 platforms (including desktops, PDAs and
embedded devices) and, precisely because it has to run on 20 platforms,
takes cares of all the above (including screen size, rotation support,
B&W operation, etc., etc.) itself independently of the OS on which it is
running. The harder you make applications to port the less likely it is
that people will bother. By all means expose your special features via
a documented API, but the list of special features that you say
D-Bus support will be necessary for aren't that important for many

Maybe - but no platform ever succeeded by making it harder to write for!
Seriously, for many applications as long as they can be easily installed,
launched, given a window to draw in and somewhere to save their state,
it doesn't matter what OS/environment the app is running on and
especially in the early stages of a new OS/environment you want it as
easy as possible to get content on. If I can do some small tweaks to
an existing Linux port rather than a full new port then it is far more
likely to happen.
Anyway, just some random thoughts from someone who needs to sell the
concept of porting to a new platform to a sceptical management with
no additional budget.
