Hold your horses, until it's released Ethereum is nothing but vaporware, when/if released it will then go through a testing phase and then it will need to live up to the expectations, several years will pass until the software pass all the tests and prove to be reliable software.
Ethereum is not vaporware.
But yes I agree it will take several years for Ethereums potential to come to fruition. Still...very exciting times.
Ethereum has admited they are stuck in certain key parts of the devlopment. I still dont get why someone would invest in Ethereum instead of Maidsafe.
