I wouldn't say that.

Dropbox is good because is ridiculously simple. I've been using Windows 8 + Skydrive full time and well, it's not a sunshine.

It's buggy, and just upload files (not folders) and I don't believe it will get so much better after the official launch.

And yes, Dropbox is probably screwed. I've been using SugarSync just because it gives me more free space.

If google drive is just as good as dropbox, well, you know the drill.
