In this document we only discuss main Linux problems and deficiencies while everyone should keep in mind that there are areas where Linux has excelled other OSes (excellent package management, usually excellent stability, no widely circulating viruses/malware, complete system reinstallation is not required, free as a beer).

This is not a Windows vs. Linux comparison however sometimes I make comparisons to Windows or MacOS as the point of reference (after all their market penetration is in an order of magnitude higher).
