As long as cars need fuel, its price (as insurance’s, maintenance’s, taxes…) ought to be added to the total cost of owning one.
Cheap gas or lower taxes do not guarantee any given car is better than other using a different type of fuel or subject to higher taxes.
It’s the total ownership and driving experience what matters.
And, by the way, the fact that a given fuel type today might be cheaper than another does not ensure it won’t change in the future, once the car has been bought.
Not really sure smartphone users have really analyzed their potential expense on apps when they decide to buy one.
We do not therefore think this is necessarily going to provide any effective help to Windows Phone 7 in its struggle against iPhones or Androids… and we are not really sure this is going to make very happy developers, as their financials won’t have the same prospects as the ones provided by developing for Androids or iPhones.
