So far, it is pretty impressive. It is extremely lightweight, and as you said, it's compressible. I've taken advantage of the compressibility, stuffing it into my already-full backpack. I like the collar, as it serves to keep my neck warm. I wasn't sure which size to get, as I'm between medium and large. I chose large, and that was a good thing. It has room for sweaters underneath. I'm a little concerned that it is long enough in the back, as most cycling specific clothing usually is. Also, I expect it to have reflective features, and the only one is the logo on the left side of the chest. I'll put some of my own reflective material.
So far, so good.
I need it to be warm and windproof but most of all breathable. I suspect this will be breathable, which means I need there to be a limit to how much heat it retains. My ski jacket gets much too hot even when I'm not cycling all that vigorously.
Feel free to nudge me in a few weeks. 
Cool. I found it the most breathable thing I know of. I like the collar too as it is always comfortable. I am 200 lbs. ant 5' 11" and I use a large, but I do not put heavy layers under it, just a light layer at most. I do sometimes put a ski coat over it though. You are right that to have great breathability it cannot be totally windproof. I wear a loose waterproof shell over it frequently for reflectivity and more windproof-ness. I do not often wear it as my outer layer when biking. I do find that the sleeves can get clammy at times so a long sleeve poly tee is good underneath it. See my note above for how I can easily dump a bunch of heat and sweat before it all condenses and gets clammy. I agree that some additional reflective material would be a nice plus. I do not have a problem with the shorter back as my rain shell covers that.
