I’ve used OOo since the beginning (1.something) and I set my default documents to MS formats. I send documents to clients to edit on occasion, in Word format, but all of my official correspondence, invoices, etc., are sent as pdf files. One of the big advantages of OOo, is the ability to create pdf files on the fly.
Tongue in cheek, as I was in another thread on the cost of Vista Ultimate…
Amazon’s price for Microsoft Office 2007 = $414.99
The price of OpenOffice.org = $0
Freedom of choice?
Priceless.
