Another scenario which is probably much more likely is PHI is kept on a secured server. Client computer becomes infected. PHI was never compromised. Does that still trigger a notification?
Precisely this. I'll use 3 examples from current clients.
We've been fairly fortunate in what customers ended up infected with and have actually arranged things so there's very little impact if customer end-users end up infecting a local desktop via streaming a radio station or the like, but if customers have to report breaches for infections even on systems that don't have patient data stored or accessible that's going to turn into a real headache.
I have one and use it on a daily basis, but primarily as a SIMless podcast player using PocketCasts (which I still hope to see one last update for....).
The lack of apps is the big thing, and a couple of the ones you mention may become more problematic in the near future
There are other more niche apps I'd like to have which either aren't available or can't be available due to the security model - things like SMS, call log and decent location tracking.
As for other aspects, for a Microsoft phone running Outlook it has a terrible time with calendar sync - I'll add a calendar entry on an Android tablet, it'll sync to my company Exchange server, show up on my Android phone, then show up on the Windows phone hours later after the event and only when I actually open the calendar app to see why I didn't have a notification on there. While the keyboard is better than it appears at first, it still has some gaping holes (such as not showing the "secondary" characters available by swiping on the keys).
I don't feel bad about having purchased the phone and might do it again under the same circumstances - it was $80 and I got a free 1-year subscription to Office365 with it, and my previous phone was showing signs of dying - but with the current status of Windows Phone and the application environment I can't imagine the scenario in which I'd actually buy one to use as a daily driver.
