Nice to see other ubuntu users her on JUB.
I've been using ubuntu since Hoary 5.04.
Feisty 7.04 great! I've been testing the 7.04 development version for a couple of months prior to this release and it works very well.
If you are new to Linux and open source software there are a few things you should know before you consider trying it out.
1. Ubuntu is NOT Windows and is NOT Mac OS. Though,
It's just as easy or easier to use than Windows or Mac OS, provided you realize that it's different and take the time to learn the difference.
2. Ubuntu Linux is free as in beer and free as in freedom and is currently used by millions of people around the world. There is a new version released every six months. There are no software keys or activations needed. Make copies of the install CD and give them to your friends & family or use ubuntu for your business or organization. You can even hand out copies out on the street if you want. It's all permitted by the license.
3. Ubuntu will run on both PCs & Macs including 64bit systems.
3. Most of the software you will ever need to install and use is also free and open source. Ubuntu is preinstalled and ready to go with multimedia and office software (OpenOffice). If you enjoy paying for expensive, proprietary software ubuntu linux is not for you, but I'll be happy to take your money

4. You can test drive the Live CD without installing it on your computer. Just boot up your computer with the install CD. It wont install anything unless you choose to install.
5. It is fast & simple to install and very easy to use.
6. You'll be getting your support from a community of users/developers rather than a company and you'll have a chance to help others as well. The Ubuntu community is terrific at solving problems and helping people new to Linux.
7. Unlike Windows and Mac... Ubuntu will automatically keep your entire system up-to-date, i
including all of your installed applications.
8. Choose from thousands of free applications in the ubuntu software repository that you can search/install/update/uninstall with just a couple of mouse clicks.
9. Linux is tough on security... you will be safe from viruses, spyware and malicious scripts that plague Windows users.
10. Lots of hardware will work right out of the box... No need to download and install drivers like you do with Windows.
11. You can run many Windows applications and games in ubuntu using WINE if you can't find a suitable alternative in the ubuntu software repositories.
12. Sharing files and printers with Windows/Mac/Linux machines is simple and easy.
The list goes on and on... If you have any questions let me know.
