Linux.com argues that Synaptic is Debian's best weapon for the DCC to get an advantage over other big Linux players.
You may agree or disagree, but the story is found here.
Sadly, it looks like the RPM/DEB divide is going to be with us for a good long time. And with Red Hat and SUSE both on the RPM side, and with Red Hat and SUSE's parent, Novell, doing a high percentage of the world's enterprise-oriented Linux advertising and PR, RPM is probably going to stay the dominant package management format for commercial Linux users, and the software developers that cater to them, for many years.
This means commercial distribution vendors working on the Debian side must work extra-hard to make life easy for their users.
Synaptic (combined with APT) is their secret weapon — if they choose to use it. It has matured to the point where I like it better than the Windows add/remove software utility, SUSE's YaST, and all others I have tried. I suspect that I am not alone in my affection for Synaptic. It is a good, user-friendly program that does an essential job — and does it well.
If DCC Alliance members actively support Synaptic, as a group, they will have a mutual competitive edge over their RPM-based competitors (and Microsoft). They will also make free Ubuntu and free Debian more popular, which will increase the demand for .deb-packaged software, and this, too, will help them increase revenue.
