Seems simple, but can throw newbies sometimes....Over the last year, for example, I have:
1 - Used MS Word, then...
2 - Used Google Docs, then...
3 - Shifted to Open Office

I still use Word/Notepad (I gave up MAC's about a year ago when my MacBook ate iteself...) top copy/paste/remove extraneous formatting/links from research material.

What do you use? Pros/Cons?

My current favorite is the Open Office text editor. I like it since you can embed links and HTML formatting (H1, H2, etc)...
I don't like that it won't run fast on a machine that doesn't have a lot of RAM (it runs off client-side Java)
