It did well ... even coming home in the pouring rain! I expected to see run marks in the minerals (like you'd expect with water/powder) but nada. Now, I took an afternoon nap, and when I woke up, I noticed that I had a more dewey look to my face which I presumed was my skin's natural oils. I tapped just an itsy bitsy tiny bit of the mineral veil into the cap, swirled, and buffed it over my face and voila!
I'm not surprised that (with my t-zone) I'd need to touch up mid-wear b/c I've always had to do that no matter what foundation I use. But as far as "coverage" goes, this stuff gets an A+!
I think it will come down to this (for those on the fence about whether to buy it or not) -- if you DON'T like the cakey-ness of liquid foundations and want a more long-wearing, natural, youthful, airbrushed, dewey look to your make-up, you'll love this. Also, the chic at Sephora said that with routine use of the foundation and skin revver-upper stuff, you will see an improvement in skin tone, texture, etc. over time, that you'll experience less breakouts, skin irritations, etc.
If you're happy with your current foundation and don't really give a rats patookis about the aforementioned characteristics, save your money. :shrug:
Now I'm curious about ease of application. 
:kindredspirits: Does that make us gay? 
I spent over $100 in that dang store! The least she could've done was throw in a little mini-lipstick or some crap! 
I had to dig thru a few links before I found one that wasn't expired or one that wasn't already covered under their current promotion like free s/h and free gift wrapping.... I'll keep digging and will post it. It was an awesome satchel full of free stuff...
