I don't yet have a good answer to this.
My kids are getting to the age where a lot of their homework is online and given I have 4 children, my laptop and my wife's are getting over-utilised so for Christmas we put all our money together to get them a macbook pro to share as Macs IMHO just take
a lot less maintenance than Windows machines which is essential in a busy house.
Anyway, I was looking at signing my son up for Windows Office 365 for free using his school account but his school haven't signed up to it so it's a no go. The Macbook came with Pages as you say and it looks pretty decent so we'll give that a go for now
I think.
I'm not sure if my Mum's Macbook has it but I will check. I imagine there will be conversion issues but perhaps worth exploring certainly for my kids who don't have critical requirements for things to work exactly but probably not for my Mum.
