It'll be tough for Dropbox. I imagine the #1 thing they have going for them is a strong consumer-facing brand and a bunch of existing customers (who are likely still telling their friends to download Dropbox, though who knows how fast). I also suspect they're working on a full office suite - they acquired Mailbox and Hackpad more recently. Amazon doesn't have much strength as a consumer-facing tech brand, afaict. As a developer, I trust S3. But as a consumer, do I trust Amazon's software to be usable or reliable? I'm not so sure. Still, long-term, I find it hard to see things panning out for good ol DBX without something big coming out soon...
