Linux simply thrills me. If you think about, which operating system you should use to surf the Internet, send e-mails, do office work, then this and much much more can be done very well with Linux. There are various flavors of Linux. I prefer to use Debian for servers and desktop computers.
...may look like that you download from the Internet an ISO file of a live version. Burn it to CD or DVD - depending on the amount of data. Keep in mind not just to copy the ISO file to CD or DVD with 'copy'! Then restart your computer from these burned CD or DVD. From a live version nothing will be installed on your computer. If necessary, programs from CD / DVD will be loaded, which takes a few seconds. If you have Linux installed once, then the programs start faster than from CD / DVD.
...may come from the fact that it seems to be more difficult to install and to configure it. Ther is no dic partition like C: or D: as You may know from Windows. There is no Folder like C: \ Program files. Your folder with the personal files is not at the same place, as in Windows.
Imagine a funnel, in which you enter by the narrow/close end. Like this it may be, if you begin to use Linux. The further you progress, the more you have a wide panorama.
You can get all free. No licensing fees. No compulsory registration.
...then you should first back up all data. You should know something about the partitions on the hard drive. It is quite possible to install Linux alongside Windows, for example. When the computer starts it shows a query so that you can choose between the two systems. It is also possible to remove any other operating systems and to have only Linux on the computer.
You can even use a program written for Windows and install this program on Linux (with 'wine' - wine is not an emulator), if it is absolutely necessary for to use a windows program. This is not an issue to begin with and unfortunately does not work with any Windows program. Just for fun I've tried this: Word 2000 on Windows requires a lot more time to be launched as on Linux with wine (two seconds), in Adobe Photoshop is the difference more clearly. The meaning and purpose of Windows programs under Linux can philosophize long.
Or you can create your Linux an environment in which you install a virtual machine (Virtual Box). Virtualbox can be installed on your Linux or your Windows system. It is a program that allows you to install other operating systems in a special environment. The other operating system 'means' to be in a single housing. You can then install a different version of Windows or Linux and just a start while your currently installed Windows runs. That's is also nothing to begin with.
There are still many issues about Linux which I don't know. This may be due to the limitations just mentioned. Unfortunately, there is not a driver for each device, that may be a wireless or video card, or a scanner. With variants like Ubuntu or Linux Mint Debian (my favorite for desktop computers), it has become relatively easy to install a Linux operating system.
...that it is a robust system, in which all major programs are included for a workstation. With Debian You get a graphical user interface with an e-mail client, office applications which allows to read an edit files of various other Office programs, in short - a good basic equipment. The system is relatively robust against attacks. Anti-virus and firewall comes without extra costs. You can install it on as many computers as you want.
In Linux, there are unfortunately errors in the programs, as they are in other operating systems. Which if solved, will be eliminated relatively easily via an update. In most cases the computer don't need to bee rebooted. You can even connect via SSH to a remote computer on your network and perform an update while someone is logged into the system and works in the graphical user interface (GUI).
