Do you understand that a barrel of crude oil has to be refined into gasoline, kerosene, jet fuel, heating oil, etc? Do you understand that it then needs to be transported to stores for retail sale? Do you understand that those things are not instantaneous? Do you understand that when the price of crude oils goes down, the gasoline purchased last week doesn't retroactively cost less?

Regarding Rovio, maybe the owners will siphon off the extra money. Or maybe the company will use that extra money for more employees and to create extra levels and updates (benefiting the consumer, you might say).

I, like most of Rovio's customers, do not live in Finland and will probably never visit so the tax money doesn't benefit me whatsoever. I don't live in Ireland either, but Ireland, as one of the PIIGS, is an economic basket case. If Rovio pays a 12% rate to Ireland instead of a 25% rate to Finland, that could help stave off the destruction of the European Union and prevent a world-wide depression.

Or business men before computers -- they tell their secretary to make a phone call, check their calendar, take a memo, find an abortion clinic, etc.

Then ask yourself -- is the future a phone/pda/goggles with a keyboard or with natural language processing?
