Performs efficiently but requires overcoming a learning curve
There are many differences between Ubuntu Linux and Windows as they are totally different systems. You need to have more knowledge about Linux before using Ubuntu Linux. Although it is designed as a desktop system, basic knowledge is still required. Windows can be used by any layman, which is the main difference. I do not know much about security breaches or potential issues. The Wi-Fi and wireless capabilities work perfectly fine. Excluding the learning curve, I would rate it a 10. However, considering the learning curve, I would give it a six or seven. My advice would be to have patience. Overall rating: 10 out of 10.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Flatcar's support is good. The version I am using is stable and allows us to make needed changes."
"The main distinguishing feature between Ubuntu and other Linux distribution is that Ubuntu has excelled at user-friendliness. It's very easy to use."
"The most valuable feature of Ubuntu Linux is the price because we don't need to pay as it is used for selling equipment."
"The solution is easy to use"
"Ubuntu Linux is easy to start, and MicroK8s is easy to deploy. Plug into the back-end storage and networking is also easy. It is good to start with 3-4 nodes, but hard to scale. For production grades like 20 or 100 nodes, we go with the RedHat for on-premise."
"Ubuntu Linux is more secure and has additional security features than some other operating systems."
"Ubuntu is great because you get most of the packages or software you need. You get the latest updates and stuff fairly fast."
"Ubuntu Linux is very easy to learn, manage, and keep updated."
"The initial setup is simple."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"More drivers for hardware such as different network adapters should be developed."
"There should be more integration with other operating systems applications."
"I would recommend they improve the network security, because it can be very difficult. I mentioned that when you upgrade Ubuntu, the network cut is always deactivated, so you have to restart the service to reactivate the network. It is important to improve this ability."
"It could be easier for beginners and the user interface could be more user-friendly."
"When you talk of some of the flexibility, like you want to install from scratch, Windows is more user-friendly compared to Linux."
"It could always be a bit more secure."
"The product must provide integrated security solutions."
"More security features are needed to protect the current file system to prevent attacks."
