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."
"Ubuntu Linux is an easy-to-use solution."
"The solution has proven to be scalable. It can scale quite well."
"The solution is scalable, it is open-source, and can be developed. You are able to install it on many different systems."
"The most valuable feature of this solution is that Linux has cost-effective licenses."
"The initial setup is simple."
"The integration with other applications, like Chrome or Firefox, works excellent for users navigating and test browsing."
"The solution is free to use and open-source."
"RTO with the use of templating support for VMware for fast deployment of recovery or new systems, with the least amount work needed on custom settings, within application installed from install repositories. Shorter overall time with the vetted packages. Normally install and go."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"The solution could be more user-friendly, as I use Mac on a day to day basis."
"When installing software, an online interface has to be used and commands written to run the installation. The solution could be improved if it was possible to click twice in an icon for the installation process to begin."
"The stability could be improved."
"Ubuntu could be improved with more container integration and orchestration of those containers. We are looking to have more cloud-based solutions, like Docker, and container-based solutions, or Kubernetes-based solutions integrated with Ubuntu. Instead of going for VMs, we would like to have more container-based solutions on top of Ubuntu."
"It could always be a bit more secure."
"The solution could improve by being more secure."
"More drivers for hardware such as different network adapters should be developed."
"One thing I've noticed is network connectivity issues where packets are sometimes lost."
