The Old Geek has a friend who's worried that his Microsoft Office subscription will expire and lock him out of all his documents. Is there a way around this? Leo says that even when Office expires, he can still open his documents, he just can't edit them.
There's another option, though: Microsoft Office online. It's free and works just like the Office subscription, but with some limited features. There's also open source office alternatives like Libre Office. It's free and works just like Microsoft Office. So there's nothing to worry about. Buying Microsoft Office these days really isn't as compelling as it used to be.
