Why would anyone buy office when there are free alternatives such as OpenOffice and Libreoffice?
Because people have personal preferences. I use MS money and have for years, my brother uses another software brand. I used ghost for years as he did also. Then he went to acronis, I eventually switched to Paragon. Just in the same way you like Apple another person may not like it. I am not saying 1 is better then the other, just personal preference. I use MS office. I am happy with it. I am used to the software and have been using it for a long time and don't plan on switching just because open office is free.
Maybe this is hard for you to understand, but try.
You can reply Ripley, I won't bother replying and get into some forum tug of war with you.
