I spend a good part of my day in one variant of a gnu/linux environment, whether it be development of apps (for which I use GNU/Emacs), or on a server administering stuff (which technically isn't gnu/linux), so having my fashion phone in kiosk mode feels pretty good, actually. I think I'd be pretty unhappy if the stuff I count as "work" in my mind bled over in to my personal life, and I love not having to jump through the same types of hoops I do for work just to make a simple phone call or send a text message.
