I’ve got a mac with parallels and windows 8.1, I pay £7.99 a month for Office and it gives em all the office suite of products for 5 users, so I have Office on my mac, office on the virtual machine, one on my daughters laptop and one on the iPad, as well as 1tb of storage on one drive.
I barely touch the VM now, everything on the mac side of it.
Or, before hand I used open office which is free, really easy to use and is a virtual copy of office. The only time it won’t convert anything to office is really heavy spreadsheets with loads of formulae embedded.
As suggested, I bought a £20 Samsung DVD player from Argos and works a treat.
