boto cheat sheet

I've been using python boto for nearly a year and have been greatly impressed with it from the get-go. However, I usually find myself forgetting key methods and parameter for the few AWS services I use the most, namely SQS, DynamoDB, S3 and EC2. So, in order to avoid going through the documentation every time, I made a cheat sheet for the most commonly used methods and functionality of the above said services. You can now download it here. If you see something amiss or inaccurate please let me know.
