Improving growth does mean either Microsoft's doing something right and/or the size of this market is increasing. But seeing a growth number this high means you should be very skeptical that cloud products will be able to carry the rest of Microsoft on their back going forward, or successfully challenge market leaders.

places Sky Drive in fourth, behind Dropbox, Google Drive, and ICloud....
Admittedly I'm referencing data I read somewhere which I can't find right now, so I'll retract the statement about SkyDrive being the biggest. It is certainly up there though and growing according to this financial report.
Or Hotmail. I don't use Windows, but I use Hotmail and I have some files stashed away on Skydrive. This is stuff I don't access frequently where it's fine to go through the browser to get them.
I even tried it on a Mac, but it needs a case-insensitive filesystem. Amateurs...
But it's more than that, SkyDrive was launched in 2007, DropBox 2008. In classic Microsoft style, they didn't really tell anyone it existed for a few years.
I'll be honest, I don't 'get' dropbox. Their security record means I'll never, ever trust them with anything beyond a lolcat, they don't really have any killer features.
The fact that on Windows SkyDrive offers much better user experience than DropBox, the implementation of JIT-downloading files, the fact it hasn't messed around with ASLR in my web browser.
I gather dropbox is better if you run OSX, but at the end of the day having 1% of windows market is better than 10% of OSX market.
I'm sharing some vacations photos with Windows, Mac, Android, iPhone and Linux users.
The only one lacking a first party client is Linux. There are 3rd party ones serving it.
For simple sharing, it can be done entirely in a web browser. In fact for photo sharing SkyDrives web-based offering is much better than dropbox, from handling of exif/geotags to the whole commenting and such.
Most apps I use, will happily use SkyDrive, DropBox or Google Drive. As a business, why would you ever tie yourself to the fait of one. The 'key risk' is simply to great to be tied entirely to one vendor or platform. It is one of the best arguments for making AppStore Apps multi-platform.
Which brings me back to my original point. SkyDrive has some better features, even if you only use OSX. Both Google Drive and Sky Drive are working on converging the web-app space. When people are just in a browser the word / excel / ppt / etc document editing ability (all free) is considerably better than google docs.
For sharing simple photo album, its much better, especially if you want to share with someone who can edit. It also blurs into almost facebook territory with the comment system too, but has better privacy.
I can't think of one feature in fact that would make think Hmm DropBox is the best for this. As I don't have a mac to compare, combined with my deep loathing of the UX/Design Language of OSX, I have only glanced over the feature sheet. Can't see anything SkyDrive is missing on OSX that dropbox offers.
