Having used many different word processors across the decades, I wholeheartedly agree with the "won't betray me" comment. So many products have risen and fallen in the past forty years that an open and documented file format is essential for the products of our labour to have lasting value. The cross platform support is also liberating.

As for the unintuitive UI, it is a complex product that is designed to meet a multitude of needs. In that respect, it is not all that different from Microsoft Office. (If anything, I find it to be slightly more intuitive than Microsoft Office since the means of achieving some things in Microsoft's product is downright quirky.)
