Professional CDN's do anycast so first load will be pretty sane. My problem is, areas like Australia are part of very few CDN networks. Most of them are a lot more expensive. For my Australian viewers it makes sense to use Akamai or have an Australian server. For my European viewers I am best having the assets served directly off my European servers. For other viewers I may be fine using a budget CDN like maxcdn or OVH's currently free in beta CDN.
This is my motive for such a solution. Plus I have the benefit of it being able to routing around problems with little manual effort.
Just the Tegra 4 / 5 roadmap gets me excited for performance on such devices. The competition improving on Tegra by sometimes 2x. We are in for a real treat.
