Free, elegant and functional, but with quirks.

I was expecting this to have in-app purchases to unlock its full functionality, but I was pleasantly surprised to see that its completely free. The Notification Center interactivity is a nice bonus too.

It has some minor problems however:
Searching cities is broken.
Its missing a lot of cities, like Cupertino or Voitsberg (but it has an Apple Event "city" which is nice during WWDC!)
Non-standard and potentially confusing abbreviations for cities.

Also, Im concerned about the reports of incorrect times from the other reviews, but I havent seen this issue yet.
