If you are planning to replace Windows with Ubuntu then the first thing you need to do is to think about what you need the computer for? Do you need to use office applications like Microsoft Office, Photoshop, Illustrator, etc.? or you just need the computer to browse the Internet? I think answering those questions is important before making the switch from Windows to Ubuntu because from that will depend your adaptation to Ubuntu.
Pros of using Ubuntu
- No Viruses, and good security
- Easy software management
- Very Fast
- Nice looking design
- Less learning curve than other Linux distributions
- Good Privacy
- Open Source
Cons of using Ubuntu
- Not good for gaming
- No Microsoft applications
- Need to use the Linux terminal to do certain things
- Some Hardware might lack drivers support
Some people install Ubuntu alongside Windows , and boot to either instance depending on what they need to do in the computer at that moment. Linux has a replacement for most of the applications that only run on Windows, for example for Microsoft office there is LibreOffice, for Photoshop there is Gimp, for Illustrator there is Inscape and so on but the learning curve is too much for many so they give up using Linux and go back to using Windows again.
