Perhaps it is because given technical capability, I cannot understand why Amazon is even being discussed when it is technically inferior to what Joyent offers and Amazon is the most expensive provider.
Sounds to me that your understanding is the real problem here. There are a lot of resources you can use to read up on the value proposition, and while I do think AWS is pretty expensive and perhaps priced a bit too high, it's a great platform that goes way beyond just the speed of the VM tech.
