If you know DropBox, you know SkyDrive. In my 5 minutes cursory look at SkyDrive I can see it being a real challenger for DropBox. Or another way of looking at it is, why not have both?
Conceptually they work the same way. But there are some immediate advantages to SkyDrive as well. For one thing, there is more free space (7 GB to start with, instead of 2 GB). And you can more selectively control sharing. While I hear this is/has changed in DropBox, their permissions has always been very rough. Basically giving somebody shared access to a DropBox folder lets the other person control the folder’s contents, and all the sub-folders and files therein. SkyDrive has more selective settings it seems.
SkyDrive also lets you create Word and other Office documents via the web, much like Google Docs. I haven’t checked to see if there is collaborative editing or not.
There are also search features (though it was not able to find a word in a test Word doc I created via the web UI). Photos uploaded can also be automatically resized, which is nice when sharing. That worked great from my iPhone.
Google is also coming out with Google Drive, but (1) it’s not ready for me yet when I try to access and (2) the iOS apps are not available as of this writing. But I was able to immediately download and use the iPhone app for SkyDrive (which synced to my iPad) and it works just fine on both. So Microsoft has beaten Google out the door on this one.
I see a lot to like and not really anything to dislike about SkyDrive in a first test drive, except the search didn’t work on the web. Of course I never get search to work in DropBox either, so they are even on that score so far.
This is just a superficial look so far, but I say why not go for it and get some more cloud storage. I mean, why not?
