The biggest improvement on Office Live Workspace recently is obviously the new 5GB free storage. If before this you relied on Live Skydrive to keep the work document, 5GB is more than enough now to keep it. No more hassle to view/modified the document (psst..when Live Skydrive will be integrated with Office Live Workspace )
Beside the additional size, Office Live Workspace allow user creating blank workspace or folder, instead of the default pre-defined folder contained unwanted files. Again, no more hassle clearing up the folder.
And last not least, users can now directly utilizing the new cut/copy and paste to move file from one folder to another, instead of File/Move feature before.
Just choose the file, copy/cut the file, go to other folder, and paste it there. Done!
