what is it then
I've read the site and it just seems like a replacement desktop program
Hi, I've been lurking in the forums for a while gaining knowledge on fishkeeping for when my 55 UK Gal tank has cycled, but have not really felt confident in posting to any of the fish related threads, but computers is something I know a lot about
Ubuntu is part of a family of operating systems known as Linux. In the same way that when you turn on your machine it boots into Windows, when you install a Linux O/S you machine will give you a choice of Windows or Linux.
Unlike Windows, Linux is modular. For example the gui (Graphical User Interface) is just a module so you can pick and choose which GUI you want to run according to your tastes. Gnome and KDE are the two most popular. Ubuntu ships with Gnome as it's default GUI, but you can add KDE and flip between the two if you wish. You could choose Kubuntu which ships with KDE if that is more to your liking.
The thing to remember with Linux is that it is not Windows and it really doesn't handle games very well. In fact most Windows games will not run under it, so if you mainly use Windows for games then I wouldn't bother installing Linux, but if you don't play games then Linux is ideal and FREE too.
So endeth my Pro-Linux rant.
