What would you love to pay for if it was available?
diego: - A laptop battery that lasted for as long as I can stay awake (say, 24 hours).- A cellphone that people could call anywhere in the world without paying for an international call, and that allowed me to call anyone or use my data plan at the same price regardless of where I'm located. International roaming charges are so absurdly high that they force me to have different sim cards and an unlocked phone (extremely inconvenient).- A nonstop flight from Buenos Aires, Argentina (EZE) to a major city in California (SFO, LAX, SAN). I do this several times a year and the layover/recheck luggage after customs is a killer.
