A very interesting article on where the profits are going in the mobile phone arms race here on TechCrunch.  The methodology and the bias may in the report (from a DT analyst) may not be apparent, but I think the reality and the trend are true to form: RIM and Apple are now the heavyweights in the industry.  Not only are they the leaders in operating profits, but they are also the leading products which everyone else is chasing.
