There are "Waterproof breathable" fabrics that are several times as breathable as Gore (until they freeze shut or are covered with a film of water). eVent is the best. Experimental results at: www.verber.com/mark/outdoors/gear/breathability.pdf
Down is never "bombproof." If you have dry/sunny conditions most of the time (even if cold) or have an indoor retreat available, down will be acceptable most of the time - except when it is not.
eVent is pretty amazing as well as the new polartec NeoShell is looking good. There are a lot of waterproof/breathable stuff out there...some laminated some coated. They all have rating all over the map!

There are more and they all have different levels of performance, such is how many layers, coated vs laminated, and rating in regards to breathability and waterproofing. This stuff makes my head spin!
Down is certainly not perfect but there isnt anything that is. Weight to warmth ratio is high on it as well as compression, but its ability to resist water or shed it makes it lose all its benefits. This is why to me a waterproof shell around it is critical. Do I like Primaloft, Thinsulate, Climashield (also lamilite) and other synthetics...yes but they dont compress, are heavier and take way more to achieve the same warmth factor. If they get wet they still work. One insulation I am surprised has not been seen in more garments is Thermic Micro...like down but synthetic so it compresses good and keeps you warm even if it gets wet! I have only seen it in sleeping bags so far. There is one jacket but it isnt more then a ski jacket with this stuff.
One comment I got from a buddy was an age old one: "Buy once, cry once" Get a good jacket that fits your needs that has the best performance you can get...and own it for years!
