I love the latest versions of Word. Navigation is different, but I had everything figured out in an hour or so, and after that it was easy. You can download a trial version of the latest MS Office, and try it out. You can even try it out online, and there's a full tutorial on the Microsoft website.
It's just as easy to write a novel using Word as it is with any other word processor. Yes, Word has a lot of bells and whistle. Some are highly useful, and some aren't, but you simply don't have to use any you don't need. Writing a novel in Word is a matter of opening it and writing. And Word does many helpful things that other writing program can't do nearly as well, or can't do at all. And Outlook is the choice of professional editors and agent. With it, you can send and receive perfectly formatted stories.
I haven't found much that Dragon doesn't work with, and I often use it to run everything on my computer. It certainly works perfectly with every program in MS Office, and I write a lot of e-mails using it. But I can't write fiction using Dragon. My mind just doesn't work that way, and I can't think of anything to write. I think MS Office should be on every writer's computer.
Having said this, while I use Outlook on a daily basis, Word is often what I put my writing into after it's finished. I need Word's tools for dealing with editors, but I do most of my on computer writing with Q10, and no word processor is simpler, more minimalist. Word is fantastic, the best there is, for dealing with agents and editors, but you can write a novel with any
word processor. Q10 lets me write everything with no hassle, and zero bells and whistles, other than one bell that makes the computer keys sound like a manual typewriter. http://www.baara.com/q10/
Writers spend way too much time worrying about which program to use. Any program will do for the writing itself. Novels are written with wetware, not software.
