My new PC came with a trial of Office Professional Plus 2013. The only apps I use in it are Word, Excel, Outlook, PowerPoint (v rarely). Don't use OneNote, but can see a use for it if I ever buy a tablet or smartphone. It doesn't look worthwhile renewing Office as a one-off purchase. let alone taking out a sub to Office 365.
If I did let the trial expire or terminate it early, will my documents still be available for use? Could I just download Word, Excel and PowerPoint Mobile and OneNote apps from the Store as I did on my old PC? And could I also download some version of Outlook to manage my e-mail and calendar?
