Depending upon the technology news sources you read, the product may or may not be worth the wait, Office 365 subscription or not. However, if you’re still looking for a viable solution to read Office files on your non-Windows devices, check out Documents to Go (from Dataviz and my personal favorite), Quickoffice (publisher by the same name) and Office Suite (Mobile Systems). You can find these on Google Plan and Apple iTunes.
This is not unlike the other apps in the Android marketplace, such as Documents to Go, Quickoffice, Documents Free and Office Suite. These range in price from free to $20 US, depending upon whether you want to edit or just view, and whether you have an Android or an IOS device. I’ve not had much success with the freebies, but the dollar investment in the non-Microsoft solutions is pretty accessible for most people.
