Per T108425, we should investigate how hard it would be to incorporate mobile pageview data into Mr.Z-bot's popular pages reports. Right now these reports apparently only show numbers for desktop pageviews.
Pagecount data that includes mobile pageviews can be found at http://dumps.wikimedia.org/other/pagecounts-all-sites/. Would this data be easily digestible by the bot or would it require significant data parsing? Hopefully this question can be answered by asking people like AlexZ (the maintainer of the bot), rather than digging into all the code.
