I think you may have misunderstood me (my fault, in that case)--I meant that WP10 has not fixed the music cracking during playback issue (that's been the overwhelming report on this forum). In fact, you're the first person to tell me the music cracking was fixed "in some cases" with an 8.1 update--it certainly wasn't for me, and anyone else who's told me as much later changed their diagnosis. :eck:
As I've mentioned in the past, though, this problem can be bypassed (and frankly, not everyone has the hearing to detect the issue, but it is there in every Lumia handset updated from 8.0 to 8.1).
Again, having owned a 925 before my 830, some of those trade-offs are not improvements. MicroSD versus no MicroSD, obviously, is demonstratively worse, especially given that the 925 just doesn't come with that much space--if you don't want to use MicroSD, you don't have to, but with the 925 you have no choice in the matter. I like the bigger screen, but I miss the higher resolution of the 925.
I'm not trying to second-guess your own choice, Pankaj, just point out why a lot of people, myself included, switched to the 830 from the 925. Ideally, we shouldn't have, but phones are ultimately compromises--the 830 was just fewer compromises than the 925 was, and lacked a seriously annoying glitch that Microsoft gave up trying to fix. If none of those issues bother you, that's fine--the lack of monobody in the Lumia 830 doesn't bother me (on the contrary, I prefer its angles to the 925's curved body).
