Chip magazine is also a monthly computer magazine that deals with general computer issues, and has been around for a while. It is a very serious publication, but without being dry. Chip does not "specialize" on a specific operating system, they also bring Linux news, and occasionally even test different distributions. They usually also do tests on all sorts of hardware and software.

Chip magazine is one of the few computer publications available around the world, and can be found in the US and most of Europe. I believe it is also available in Japan.
