I haven't had a problem with speed yet, but then again I use CloudFront and don't serve files directly from the server. For me its worth the money for the flexibility and the ability to scale as needed. I might be able to save a little money if I went with blended dedicated/EC2 but honestly the extra headache and latency for cross-communication wouldn't be worth the hassle.
