If it costs them $1.25, and everyone else can do it for $0.75 because they have scale and capital... that doesn't seem long-term stable.
If one cloud provider becomes dominant, Apple loses. If Apple loses market share, they lose negotiation power, and Apple loses.
The only way Apple wins is if cloud stays a multi-polar race AND Apple stays cloud-portable AND Apple retains significant market share AND cloud stays commoditized.
I'm not saying it's a bad bet (I'm sure Wall Street loves the resulting financials), but it does seem like a dangerous long term strategy, if cloud becomes more of product.
