So to summarize, the Wall Street Journal and two talking heads (apart from Mark Shuttleworth) are skeptical of Ubuntu ("a Linux-based operating system used to run servers and other infrastructure in many corporate IT departments") on phones for the following reasons: 1) Ubuntu's "popularity among open source developers" 2) Ubuntu is all-or-nothing and "switching to an all-Ubuntu-based environment wouldn't make sense for many organizations", unless you "employ large numbers of Linux developers" (see 1). 3) "[T]he real challenge is overcoming this very large BYOD phenomenon" since bringing your own device precludes bringing an Ubuntu phone. 4) "It seems overly complicated to me"
