I've have known about OOo for quite some time. But i rarely need to use office software so it just sits in my machine. I also found out about changing the default format the hard way too, oh well, live and learn. I also can use it in both windows and Linux. It comes with Knoppix and Ubuntu pre-installed if i remember correctly. And NOTHING makes me feel better than NOT buying a M$ product. Long live Open source!
Ever try any flavor of linux blackbird? Knoppix and ubuntu are pretty kewl. And they are free. Download from the net. burn to disc. Run it off the CD to see if you like it. If not, no big deal. It won't touch the hard drive. Only reason i haven't switched to it fully would be because of games. And PClinuxos can be run off a thumb drive.
