I make sure my software my company creates and sells is more or less an equivalent price no matter where you buy it from. In the age of digital delivery, it seems the correct way to do it.
Then again, even books sometimes have a 'mass market edition' for countries like India, that costs about a fifth than the US paperback.
I'm not sure it makes sense to sell at the same price all over the world. What does it even mean 'to sell at the same price', who defines the exchange rate?
The exchange rate of some currency often reflects market forces and speculation, and the purchasing power parity exchange rate can be wildly different. In some countries, such as Zimbabwe, the exchange rate with the USD depended strongly on who you were and where you bought it! [0]
Maybe you could define a hourly-rate-equivalent-price: if a Photoshop license costs $2500 [1] in the US and one hour of the median Photoshop-using professional is worth $25 in the US, then Photoshop should cost like 100 hours of work in the country where you sell it, so maybe 500$ in India and $200 in China.
True, but are they worth so much less? Do you think that any publisher would sell their textbooks as ebooks for the same price to US students and to Indian students?
Scenario - You run your software company in the US. Cost of living is X and taxes are Y. You now expand to Japan. Cost of living for a sales person is 2X and taxes are 2Y. How do you pay that person if your price is the same? Don't operate there?
