Easy, take this for an example: I can right-click a file and grab the public URL for a file from my own OS and post it (it will be a direct link to the file).
With skydrive, you have to login to the site (unless you use third-party software like SDExplorer), grab the long convoluted URL, post, and the recipient gets a link to the file junk. Other than the larger amount of free initial space, there's nothing that skydrive does that dropbox doesn't. There's also app support for android, ios, and probably windows phone (but still haven't seen that many make the jump onto that platform yet).
I also haven't seen MS make an app that allows your phone to automatically upload pictures unlike dropbox.
I don't know, I just like it better, even though I use both.
