I tried Bucket Explorer and I like it. But its not useful for me because I am on the road most of the time and I need an online storage service which allows me to access my files using browser, i.e. Internet Explorer or FireFox.

I would pay for such a service, even if you just provide retrievals using browser. I can upload the files using your desktop client to Amazon S3 and use the browser when I need it.

Nice software by the way.

Thanks for your feedback. We are working on a browser based UI, but I cannot provide a specific date for now. We hope to be able to release it within weeks (not months).
