There is an assumption here that someone would only want to use CentOS on the server. I have at least two old laptops in my house that I would love to put CentOS 7 on, giving them decent software and then not having to worry about upgrading the distro for ten years which gives the OS a lifespan comparable to a windows version, I can't though, because they're 32 bit. This is also a good way to re-purpose an old laptop or desktop for the underprivileged to use. Another thing to consider is that there are still people who want to put a 32 bit OS on a 64 bit VM instance, mainly because VMs tend to have a lot less RAM than you'd see on bare-metal hardware, and the savings in RAM usage of a 32 bit app vs 64 bit one can be significant. These would still be running on 64 bit hardware but using a 32 bit OS *on purpose*. Peter
