Sorry, I missed the web part. Yes that would be unique, although I'm not sold on it's value. Why would I want my documents on your site when I've already got them on my phone and on my computer? What's the value add there? Backup? Sharing? I get the feeling that the only reason for this is that both my PC and my Phone are clients to the "master copy" on your server.

I do like the personal PC sync though, that's pretty nifty.

(EDIT: You know, back in the day there was no way in the world my comment would be downmodded. A shame.)

I agree with your point (and with the EDIT). All the big guys (google, MS, yahoo, ...) want to host our files these days, and they provide us with sharing, storage and simple editing facilities for docs and pics. They also do communications, calendaring, news and blogs, etc. I think SMBs will want to use that infrastructure and the big issue will be (as usual) integration.

So, terpua, don't add your servers to the picture in terms of where the files live. That just adds complexity and another point of failure. I'd much rather you help me sync my devices with those services or the services among each other. Sure, this is being done already, but there are a gazillion special cases that people will need support for, and a lot of them involve syncing. I would try to find a few of those cases and make your solution simple for end users to understand.

You may be doing some of this already but I can't tell from the info on your website. There should be an exhaustive feature list on your website.

RE: web part - yes, backup, sharing and create/edit docs from anywhere (just in case :)
