Can't Linux users already use Office360? I was under the impression that Office360 was the future. That Microsoft was slowing moving their office software into the cloud? Supporting Linux seems pointless. Linux has a really small market share. I am fairly sure a lot of Linux users who are tech savvy would want to support the open source Libre Office instead of forking out for MS Office. Better places to expand would be Android / iOS app stores. Tablet devices are still exploding in growth. I could see a lot of use being got out of office software on tablets.
