DistroWatch weekely has an incredibly long review of one person’s experiences using Puppy Linux.
Most distro reviews focus on installing and using one release of a recent distro. But when people decide to stick with a distro, or abandon it after a longer period of use, the reasons are more to do with the entire distro experience, which includes the distro technology, its package management, the size and reliability of its package repositories, the ease and speed with which bugs are reported and fixed, the quality of the documentation, and the social experience of being part of the distro’s community, as exemplified by its forum and IRC channels. Here I relate my personal experiences with Puppy Linux over the course of approximately one year.
