OOo or Aaargh!?

Here's a good analysis and general round-up of why Microsoft's decision to produce an extremely spiffy and completely different interface for Office 2007 was as bad a move as a very bad move can be. For me, the killer quote is:

OpenOffice.org and Microsoft Office Currently Look More Similar Than Office 2003 and Office 2007
Training your users to go from Office 2003, or before, to OpenOffice.org, might be easier than teaching them the whole new Office 2007 system.

Just how easy is Microsoft trying to make the decision to jump to OpenOffice.org?
