A call to the GIMP developer community

I "grew up" (spent my formative computer learning years) with Linux. I've been active in GNOME's theme community, and consequently, learned my image designing on The GIMP. I am a satisfied owner of "Grokking the GIMP", and consider that book to be an excellent resource guide into the world of The GIMP, even though it covers the (now out-dated GIMP 1.2). The last few years, I have become one of the many Linux-to-MacOS X converts, and am very satisfied with the transition. I have less time to spend toodling around on different Linux distributions, and feel that MacOS X is a great median; the power of UNIX underneath, with an excellent, usable GUI on top. I still tend to be very graphic oriented still, and don't think that will ever change. I enjoy casual photography, as does my girlfriend, so I still have rather hefty image requirements. And this is where my problem arises.
The only decent, OS X native image manipulation software I know of is Adobe Photoshop, and as we all know, the average person doesn't have $699.99 to drop on a software application they'll used occasionally to hack up some wallpapers. To me, GIMP is more lightweight, and better designed, usability-wise. Photoshop only gets away with being so horribly designed because it has a user-base that's used to it. As a GIMP-first, Photoshop-second user, I constantly find myself working in GIMP rather than Photoshop because GIMP's features are easier to find, and more intuitive to use.
I feel there's a huge, untapped user-base that GIMP can take under their wing. The OS X open-source converts, like myself, are loathe to drop $700 on an application, when we know there's a perfectly good (arguably better) image manipulation application out there. The question then is, why is there not a native Aqua port of GIMP? I know GIMP is developed on a volunteer basis, but if GIMP is serious about becoming a viable competitor of Photoshop, a native port on OS X is absolutely vital. As we all know, OS X is the de-facto OS for graphic design, and GIMP is losing major competition points by missing a port on this OS.
I know its not easy, and I know I'm just spouting off fumes by not porting it myself, but the truth is, I'm not a developer, I'm a user, and I don't have time to become a developer. I just hope the GIMP community understands the importance of Mac OS's role in the future of GIMP as the best image manipulation application in the world. Because lets face it, GIMP rocks. And with a native Cocoa port, GIMP can rule the world.
