resource types that are currently supported in some form need to be documented
Looks like CloudFront, CloudWatch, EBS, EC2, ElastiCache, ELB, Elastic Beanstalk, RDS, Redshift, Route53, S3, SimpleDB, SNS, SQS, and VPC might have some level of support
Support for every EC2/RDS instance type supported by the simple monthly calculator rolling out region-by-region now. ElastiCache/Redshift still lacking support of some instance types supported by the simple monthly calculator
team currently working on me-south-1, af-south-1, and eu-south-1 support
Other partitions are not supportable with the current architecture
OSType won't be fully supported soon because describe-images doesn't yet return detailed Platform information beyond being Windows or not and we're not going to be calling describe-images on customers' private images anyways

It may become necessary to re-tool this command against https://calculator.aws which will eventually replace the SMC
