So you are in the "free tier" indeed! Keep in mind that you get 30 GB
of free EBS storage, and if you are willing to pay, then you don't
need to limit yourself to micro instances.

For example, you can still use CG1 instances (which are not free even
for those in the free tier) and you still get free 30GB of EBS
storage. You basically can mix and match free & non-free stuff in AWS.
