Not sure where you saw that you need an Enterprise AWS subscription. I didn't.
I tried Workspaces for a month and it was decent. There are a few things it does better than RDP (especially on OS X). I did, however, switch to running Windows Server 2012 R2 on Azure instead, though that was because it was effectively free thanks to BizSpark.
