Linux's advanced terminal empowers versatile usage and ongoing secure development
Initially, there was nothing complicated. It's easy since I have many years of experience with it. However, if I were a beginner with Linux, it could be completely disruptive compared to Windows.

Pros

Cons

"The development teams could sharpen their skills. They should offer applications on the net."

"I am really very satisfied with this solution. However, one thing that I would like to see improve, is to have better support for multiple screens with multiple resolutions. For me, that is the most important feature."
"It can have more security."
"Ubuntu Linux could improve by having more out-of-the-box functionality for common plug-and-play devices, such as printers. It's sometimes more difficult to plug-and-play printers with Ubuntu Linux. You need to work a bit and make some drivers work. They need to work a bit on plug-and-play devices."
"There is not a lot of support for applications in Ubuntu Linux. In the industry, most of the applications work for Windows and Mac. There should be better integration with applications in the future."
"When you talk of some of the flexibility, like you want to install from scratch, Windows is more user-friendly compared to Linux."
"They can keep improving the solution's ability to be adopted by users by adding features, such as better tutorials and integration into the system."
