Two days, two ideas. One is a device that can run applications locally. This method is relatively old, but it can attract the attention of a large number of developers with the help of the rapid growth of smart phones.

For Linux, there is no need to "Beat Windows" in the Desktop System to succeed. What it needs is to provide a practical alternative to Windows or other desktop systems. It has been doing this for many years. Today, any Windows user who wants to abandon Microsoft can switch to Linux to meet their computing needs.
