possibly but I expect improvements over time and as of now I'm pretty sure it uploads full res pics instead of the scaled down versions that "share with skydrive" does now,
It's ability to delete folders on skydrive and make new folders is nice as well. It's also faster navigating uploading a bunch of pics than it is from the Picture hub
I like the fact that I can access my SkyDrive on my non primary live account without going through the browser. It seems kind of pointless for the primary account though.
