Crashes less than iOS and is as simple/straightforward to use. If I find I'm lacking an app I'll write it (although Rudy Huyn is doing a good job bettering other apps). Camera beats the spots off Samsung. Build quality is second to none.
What is interesting, having used both a 520 and a 925, is that a 520 is surprisingly good. Really, it is. The screen difference is ignorable, its performance is great and the only really discerning points are the cameras. Oh, and my technophobic partner can quite happily use one. My only issue is that when I force her to upgrade she'll be moving to an 8X0 for the camera button.
1) Swipe the screen down, hit all settings, scroll down 3/4 of the list, hit *ease of access* and you've got a slider, you can pick your own text size.
2) Click Store, type "Files", install to give you on phone access. Plug the phone in and it uses MTP which is even good enough for the car stereo in my economically priced car. Also, you have their touch sharing and beamer software...
