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 system works great with perfect stability."
"I like the flexibility."
"It is more powerful because you have more control over it."
"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."
"The product’s stability is valuable."
"The tool's valuable feature is its pro security features. I also like the way it serves the infrastructure. The main thing is that each new update or version ensures it comes out with zero vulnerabilities—no high, medium, or low vulnerabilities."
"I think Ubuntu's main strength, as opposed to using the other Linuxes, has been its ability to encourage user feedback."
"They have provided a new interface, which is great."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"I want more insights and security features in the pro version, specifically activities and vulnerabilities. When releasing a new version, it's crucial to ensure no vulnerabilities. Sometimes, a new version may have minor vulnerabilities, like one medium and one low. These typically take about two weeks to resolve. More regular patching, especially addressing security vulnerabilities, is essential to improve."
"Sometimes certain tasks are challenging due to issues with the command-line interface. Users who prefer Windows may find it difficult to transition to Linux."
"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."
"The user interface must be more user-friendly for non-technicians."
"We don't have any support, so we search for answers online. However, it can sometimes be a little messy to find the information if you have a highly specific question or a strange problem. It would be nice if finding information were a little simpler. Maybe they could have some portal that could point you to where you can find information."
"The product could be compatible with Microsoft."
"The product must enable automation using AI."
"It can have more security."
