I loved to re-build some old computer with Kubuntu. Kubuntu got an UI will be very similar with Windows 10. That is very suitable for Windows Switcher and the performance is much better for Windows 10 in the older specitications. One of the problem is lack of Chinese IME in Kubuntu. I found the solution, if you only require to input chinese for Web Search or you use web app to do the wordprocessing. You can install Google IME in the Chrome as the extension. It has a lot of Chinese IME, such as Cangjie and Pinyin. Moreover, you use mouse to write Chinese character for input too. That is very useful
