Great overview and it answered all my questions when it comes to scaling for icons (and a then some). Really liked that you hit on the memory impact of assets for scaling down. It would be very helpful if that table made it into the documentation.
Thanks for the shout out on the new Modern UI Icons site Brian! Hopefully I can get even more added as developers jump into Windows 8 UX.
