Maybe I'm showing my bias given I run a network of smartphone sites, but mobile is certainly critical. I'm certainly appreciative of the mobile style developed by Russ, but I'm hoping we'll see world class mobile support in an official, supported release. The gang that could shoot straight has a mobile template and offers the ability to create a branded app. Without knowing what's on tap, I'd be surprised if we didn't see something this year from the XF team.
Mobile is critical for me. I have branded apps (TapaTalk) -- while I've installed the mobile template, I'm hesitant to push it given the fact users see the mobile style when visiting from a desktop browser. Easier enough to change, but I'm not fond of the lack of polish.
