I got a Sony DPT-RP1 digital paper yesterday. It is such a great tool to read A4 PDF files due to its large screen. The only shortcoming is that it is the Japanese version. The Japanese version has Japanese and English language and input methods, the US version only has English language and input methods, and the Chinese version has Chinese and English language and input methods.

These low-spec servers are not ideal for heavy usage but can be efficient for specific tasks. To maximize their performance, I chose Debian without a desktop environment, aiming to reduce system load.
