I successfully opened my first .doc with OpenOffice. 'twas easy and it looks very similar to MS Word.
When I opened the document, I was directed to a survey asking me a bunch of OpenOffice questions, and encouraging me to participate, even if I'm "not a programmer or a techie." That was welcome!
I sat for a few minutes with it, trying to get the thesaurus enabled, as this is one of my favorite features of MS Word, and I use it all the time (Shift F7). The key stroke is the same, I can see it listed under Tools/Thesaurus, but it's not enabled somehow. I tried to use help, but still couldn't figure out how to enable it. If someone here doesn't know the answer, I may try their emails that they posted in the survey I was directed to.
I'm excited to learn that I don't *have to* buy MS Office when the next version comes out; I am not excited about having to learn about how to get OO to work the way I am used to working with my current applications.
That said, all in all, I am very on board with the whole idea of Open Source. When I used this program today, I felt like I was a part of something really cool and that I wanted to support. I generally don't feel that way about Microsoft, but don't get me wrong - I'm not a big "down with MSFT" either - if people are happy with it, then I think it's fine.
I may tinker around with it for a few weeks or so, to see if I can work with it easily enough, and then decide whether or not to keep going forward with it.
I may decide to slowly learn with these applications, and then when my current Office Suite is outdated - move to OO altogether.
