I'm using Dropbox right now to synch files/folders between multiple devices. The thing I don't like about it though is how difficult it is to add folders OUTSIDE of the "Dropbox" folder. I don't know about anyone else here but I don't use a folder called "Dropbox" at the root of my data folder. I also want to synch folders where they sit, for example X:\Games\UO\Razor\Macros, X:\Games\UO\Razor\Profiles, X:\Games\UO\EUO - not X:\Dropbox\NowIHaveToPutAllMyShitHere.
I do like Dropbox for sharing with other people though or making files that I might need from time to time available anywhere (e.g. installs, etc) just not to synch a working folder.
Google Drive and SkyDrive I have only used as file repositories, I haven't installed the client agents yet. I like them both for their ability to edit files without actually downloading them to the PC first as long as it's a supported file type. Google let's you share docs as well although SkyDrive doesn't. I still have to try the agents though to see if that will do what I want.
Dropbox would be great if a) they gave more than 2GB for free and b) allowed you to add any folder you want to be synchronized.
Man, I hate to say it with all of it's faults but BOY do I miss Mesh...
