How many instances can you run under the AWS Free Tier usage

The free usage tier on Amazon is a nice and convenient way for a quick check how AWS cloud works. But if you overuse it at the end of the months are will have to pay the bill that they sent you.

For example in the free tier [1] you have:

750 hours of EC2 running Linux/Unix Micro instance usage

That practically means you can have a one single tiny instance for a month for free. But every next will add to your monthly bill. That means that if you leave two instances to run over a month will have a similar bill to pay.
