So... Toyota, GM, Tesla, etc should all give up on building electric cars... because the market has spoken and petrol cars have obviously won out, will never be fully replaced and they shouldn't waste their time or money building things that only a very small niche of users want today?
I never said that. Not even hinted at it. I said the comparison EvilD made was inaccurate because the investment of money and effort was backwards in his example. I didn't say investment in the future whether it be electric cars or tablets was bad at all.
