It does indeed seem the perfect choice, but the downside is pretty expensive since you have 81605zq for the same price(when using cachevault & cachecade), and I doubt that the 16i / 12i will be in the same price-range, but above all I'm worried how long it will take before they'll start to test it.
Durability might be a issue too, since young products tend to have problems
