Query: this product is rubbish

I've just downloaded the 60 day trial version. And what a trail it is - for me. This is absolute rubbish and almost impossible to use. The question is - how on earth have a huge software company with years of experience managed to produce something with such poor usability? The so called 'help' is worse than useless. It is impossible to find something such as 'heading 1'. After at least an hour of searching I have given up. I thought I might give it a try - but no way. I'm sticking to Open Office.
