Ubuntu One works very nicely and is very quick and unique in it's own right. But I can't find any philosophy about it's intended usage. Something you want to share , must you always provide an email for it? In contrast with Dropbox you can just provide a public link , which makes for easy and quick sharing on forums and such.
Also if someone shares with me , that file will show up in the "Shared with me" folder I assume , this is an interesting concept but a little cumbersome at first or maybe just not what I'm accustomed to.
Otherwise the service is much like Dropbox correct? Please don't get me wrong I'm not complaining or criticizing , I will probably pay for and use the service but I'm just trying to get a grip on the concept and the intended use for this service.
Thanks.
