Heres another example:

I was on a train and wanted to play with TomTom and my GPS, so I politely put my phone to silent before I started it up because there were a few people sleeping near me. Yet as soon as TomTom started the voice shouted out "YOU HAVE REACHED YOUR DESINATION" at full volume. I was soo embarrassed!

Cross-app integration is a hot issue on converged devices. Android has classes for supporting it, so the functionality is there if devs choose to use it. I'm using an iPhone now and and its flawless in terms of this issue with all the built in apps. I haven't had any problems with 3rd party apps yet but most are pretty basic, e.g. my ebook and pdf readers can't really behave badly. On windows mobile with .NET CF there is a new library which lets you hook into system settings to watch for changes and set things, of course you can't guarantee every dev uses this functionality. And it doesn't exist for native C++ apps.
