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 solution is scalable, it is open-source, and can be developed. You are able to install it on many different systems."
"The product’s stability is valuable."
"Stability of our systems has only improved since moving from CentOS to Ubuntu LTS."
"The solution has a very good graphical user interface."
"As we have repositories in my country, the ease of use and the open source nature of the solution are valuable features."
"It is stable and quite easy to use as compared to other Linux operating systems. They have created a system like Windows. It is simple and without any problems."
"I like the fact that I can make it very secure with my own knowledge, which makes it different from Windows that does things in the background by magic, and you hope that it's secure. I like the availability of starting with Linux with totally minimal permissions for anybody and then increasing it on an as-needed basis. This is probably the most important to me."
"Ubuntu is rather stable, simple to deploy, stable, and well supported by an open-source community."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"I find the solution could be easier to use, more flexible, user-friendly, and have a better UI."
"Developing more applications for businesses could work better, but that is not part of the OS piece. Let the developers work on other apps, therefore the needs for consuming less memory do not affect the performance of this OS version."
"The main challenge is restoring the system from a crashed state, which can be complicated for non-technical users."
"The only improvement I would suggest is to switching back to Aptitude. They switched a lot of the packages that used to be running in Aptitude to Snap. I don't find them as usable when they are in Snap. The most obvious instance of this is that it's caused me to have issues with Chrome. Starting Chrome took a couple of seconds before it was up and running, which wasn't pleasant. Back when it used to run packaging in Aptitude, I didn't have this problem. I know they're familiar with these issues because a lot of other people have experienced them too."
"Ubuntu might work for a bigger company, but I don't think so. Again, you would have to get the right people to do it. You need somebody technical. If you have a bunch of people who aren't technical, then it is just going to be a headache trying to get a feel for it or teach them."
"It would be nice to see more compatibility with certain Microsoft solutions, such as OneDrive."
"The product should provide more automation."
"It could always be a bit more secure."
