After about 4 years in the making, Microsoft Office for iPad is finally here and it is free!
Free in the sense that you can view Word/Excel/PowerPoint documents, but if you want to edit them, you need to have a Office 365 subscription.
An Office 365 Home Premium subscription (S$138.00/year or S$13.80/month) allows you to use Microsoft Office on 5 PC/Macs and 5 mobile devices (total of 10 devices). Note that Surface devices doesn’t count as part of the 10 devices as they provide a perpetual Office licence per Surface.
You can download Microsoft Office for iPad from the App Store: itunes.com/apps/microsoftoffice.
