Web site browser stats are often misused to talk about OS market share, but in this case, they're perfect. They measure exactly what we want here. One set I looked at[*] says the XP:Linux ratio is about 20:1. Others roughly confirm this. I was unable to find stats that broke the Linux portion down, which is unfortunate because it's difficult to build a browser that runs on all Linuxes out-of-the-box. Netscape used to ship an "any Linux" tarball, through Netscape 4. To pull that trick off, they had to include copies of *all* of the libraries it was built against except libc, even when the platform came with one or more of these libraries. The lowest-common-denominator result didn't take advantage of any platform-specific desktop features. NS4 looked and worked like CDE/Motif no matter where it ran. Chromium doesn't try to do that. They'd have to dedicate build resources -- test VMs, develoer time -- to each OS they specifically support. They'd then have to choose to either do the sort of LCD effort Netscape did, or spend development time creating workarounds for missing features on the older platforms they want to support. To hit your 100:1 number, John, EL6 would have to be 1/5 the Linux interactive desktop market. I'd be stunned if it is that high, given how popular Ubuntu and Mint are for that. I also agree that 1000:1 seems like the far edge of the probability curve. That would mean EL6 is 1/50 the total interactive desktop Linux market. It could be that bad, given that most EL6 machines are probably headless servers. [*] http://gs.statcounter.com/#desktop-os-ww-monthly-201211-201311
