"Hello, I asked myself exactly the same question in saying to myself that if this option exists, I'll be using Office Live Workspace all the time. If not, I'll be swapping between versions on my hard drive and OLW and it'll be a real pain....
We don't always have access to the internet and it's not possible to rely solely on OLW!
Thank you."
