"The main current forks are Libre Office (sponsored by Google and Novell), Lotus Symphony (guess), Star Office (Oracle), and the original OpenOffice.org. So you can take your pick of evil overlord if Microsoft is not good enough for you!"
All the different forks should still be able to open, work on and share the same documents without any difficulty. So a number of versions is not actually a problem.
And it's nothing to do with Microsoft being an "evil overlord" and everything to do with Schools not wasting their money and not forcing parents to do the same. And there's also a huge argument about how picking up generic technical skills is actually incredibly important. In an odd coincidence of timing the Register has recently published a story that complains about how the UK is fixed in a mindset of using propriety software and how that's damaging our competiveness.
Yes that story is from someone trying to push an Open Source Operating System but the principles still hold true for Word Processing software too. And for the record I'm actually in favour of Windows being the right OS for schools to be using, it's only when it comes to the Word Processing stuff that I believe that the alternatives are actually mature enough to be used.
"If you just want your kids to get on with thier schoolwork, I'd advise you to stick with a PC and MS Office."
Increasing numbers of people are using things like OpenOffice and it's about time that schools were challenged over their IT expenditure and strong arming of parents into forking out money.
