Fair point, and I suppose that IMaaS is going to have a good profit margin, but the sheer numbers of people I know who have bought a BlackBerry handset because of BBM probably wouldn't have had it been available cross-platform.

What's the average profit margin on a phone? $100-$150? Now imagine you bought a $10/month service - over the life of a contract, that's $240? 30% to apple - that's $168 - that's would be about breakeven - not including R&D costs, etc.
