The OS-tans are an internet phenomenon in Japan where the OS-tan (or OS Girls) are the personification of several Windows operating systems.
For example, XP-tan is depicted as a dark-haired girl with an “XP” hair ornament worn on the left side. As Windows XP is criticized for bloating a system and being very pretty without being equally as useful, XP-tan wears tight clothing and has large breasts representing memory usage.
I suppose thinking about Windows XP’s memory bloat as large breasts might placate many a computer geek. So what should Mac-tan and Linux-tan look like?
