Why hasn't someone implemented a better system than the current electoral college?

I know that there are varying opinions as to whether or not the electoral college system is a good one. I don't think that it is. I know the system was implemented so that less populated states have more weight in elections. While this may seem fair, I still think popular vote would be a better option. And I think more people would come out and vote if they knew there vote was actually going to help elect the president. There may be more people in New York than Idaho, but if every single vote counted throughout the country, collectively, than the President in office would truly be what the majority of Americans want. Am I wrong to think this way? What are your opinions on this matter?
