Why I don't use EBS root instances

Recently Amazon announced a new Micro Instance for EC2 which costs significantly less then a standard small, and contains the ability to "burst" CPU usage. This new instance type leads developers more and more to using many instances to perform tasks since it's far easier to scale out.

This also marks the first Instance that doesn't contain any ephemeral storage at all, meaning you have to set up each instance on an EBS volume, and you can't simply run one off of an AMI. Additionally, if your instance dies, you'll have to fix or replace that EBS volume, instead of simply tossing it away.

Amazon points out that this method of booting from EBS is faster then copying from S3, and does provide a few advantages. While it's true that the Initial boot process will be faster, it's been tested and proved that the Ephemeral disks are faster then EBS volumes. This means that if you're doing any sort of heavy disk IO, especially temporary writes, EBS will be much slower for you, and you've got no other option for Micro instances.

I love the idea of Micro instances, and I understand that Amazon was saving money (and passing that savings on to the consumer) by not proving a large Ephemeral disk with each instance, but really not even a 10GB root partition? This new step in Amazons recent history seems to be a major step backwards, showing that EBS-backed instances will be their future supported instance of choice, instead of providing support for the disposable instance model.

If anyone at Amazon is listening, I'm not asking for much, just let us have 10GB of free Ephemeral storage for these Micros. This Ephemeral storage gives us a lot of usability for free, which is exceptionally useful for things that are temporary.
