I've scarcely touched my laptop over the winter break, satisfying my SO addiction entirely through the iOS app. (And occasionally the mobile website.) It's been a great exercise in seeing how livable the app is (and posting app bug/feature questions to MSO).
Apparently I'm earning hats, and interacting with folks who've achieved even greater feats of haberdashery, but I don't get to see any of it.
The end of Winter Bash 2014 is near, sadly, but perhaps we could consider including mobile users in the fun next year?
