Gentoo Linux Still Popular Today?

I have a set of Thinkpad X-series (x86) for a fresh installation of Linux OS. **I want to ask based on today's trend for mobility, such as android, is Gentoo development catching up with today's popularity, if not what would be equivalent to Gentoo?** Looking at Linux Distro from Wikipedia, the timeline based on initial release over 10 years are Slackware, Debian, FreeBSD, Gentoo. But the Gentoo hasn't been growing in its popularity since then. http://en.wikipedia.org/wiki/Linux_distribution The equivalent closest to Gentoo I have seen in Wiki page is Chromium OS, > "designed by Google that primarily runs web applications, using Gentoo > as its foundation." - Wiki However, though, nothing seem to have mentioned in particularly about Gentoo OS in Chromium Website. The relatable term I can see is "Portage", which is Gentoo's Package Manager. http://en.wikipedia.org/wiki/Chromium_OS **My next question is could Chromium OS be the future Gentoo-alike OS based on future key trend of mobility?**
