Heroku hasn't changed pricing since they launched, actually. The only historical price reference I quickly found was that the EC2 was $0.085/hr for (what is now called) an m1.small[1].
Heroku launched with $0.05/hr pricing.
Amazon's new m1.small pricing is $0.044/hr, nearly a 50% price drop over four years.
Heroku still is $0.05/hr, the same price as when it launched. Heroku runs on EC2.
Uh, did I miss something here? Sounds like Heroku was actually cheaper than the raw EC2 rate when it launched, and is now just over half a cent per hour more.
