What happens when you create a Blue Ocean?

What happens if Google makes a Blue Ocean out of of Google Docs and as such "makes the competition irrelevant"? What happens if Apple keeps changing the way we work (another Blue Ocean) and we keep buying Macs (which don't run MS Office so well)?

What happens if we are all tired of Microsoft putting the lock on our desktops and we prefer open source Open Office instead (my preference)?

The landscape could change (actually probably already is) overnight.
