Jonne: While you're browsing Dropbox forums maybe you could also query about addition of public links to API At least for me it would be most likely the main use case:
1) Send a file to a Public folder in Dropbox via N900
2) Press e.g. "Copy Link" button to copy public link of the uploaded file to clipboard
3) Paste the link e.g. in IM chat for a friend to open

Of course I could get the link via web interface but if it could be done inside the native client, it would be superb
