Microsoft is breaking the really old and nasty stuff anyway, so it's not that big of a deal.

Also, whose office suite is "better" doesn't matter. Can the software meet the task? Thats it... nobody cares if a government worker like Excel.

Exploring this stuff is automatically a cost-savings activity, because Microsoft will run around like chickens to save the business. You may end up getting significant concessions on Office just for asking the question.
