Today, I downloaded Ubuntu 5.10 live demonstration ISO and burned it to a disk. When I rebooted my computer, I was using Linux! In fact, I'm using Linux to make this post. Cool!
To be honest, it looks a lot like Windows. It acts a lot like Windows. But it sure is cheaper than Windows! Ubuntu is completely free, and comes with Firefox, Thunderbird, and Open Office. There are all sorts of applications that make Ubuntu a viable alternative to Windows.
While I'm not quite ready to switch, I am going to explore the world of Linux. However, so far, I'm impressed. Now all I need is a dedicated Linux box. . .
