Interesting question. I grew to love apps because the ones I tend to use all serve a single purpose. With the ability on my iphone to move them into folder with similar apps that kept things simple.
While I understand the drive to have the “one service” app, I’m concerned they’ll soon run into the same #ux issues our websites do. I don’t have the tech background to know if this can be easily addressed. I know I’d love to pick and choose my city apps and have a folder for them, although I could see value in a Transportation app (bus, bike paths, dare I say cabs? 😉
Looking forward to seeing what my city gives me…
