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.
