Re: Lumia 520, 720, 920, 1020, 1320 Owners
Well, I guess the problem here is that even though W10M in its current state may not be the best experience on the x20 devices (I wasn't initially too excited on my 925, but it got better but not up to par with 8.1 in terms of speed...) I think (and maybe others as well) that Microsoft could have done better. Of course, for Microsoft, as for any other company in the world, it is always the question: "Is it worth it? What's in it for us?" and they decided: No, it's not worth the hassle, 50% of the user base is good enough!
Too bad though that they had promised before that all devices running WP8.1 (which my 925 happily does) would get the update - watch the video provided by Satish Singh, it's an official Microsoft event one year ago! Now also, many of us were "victims" of the WP7/WP8 debacle (my Lumia 800 - a great device - sits here in the drawer and collects dust). We now feel being betrayed twice in a row.
Working in sales, I have learned that credibility with the client is one of the most important things in order to sell. For me, Microsoft has lost pretty much all of their credibility as I ask myself: what official statement from Microsoft can I trust? What promise will they keep in the future? What other "surprises" do they come up with? I wouldn't be surprised if all x30 devices that were now able to update to W10M won't be getting the Redstone update, they'll be stuck with TH2 (well, at least they have W10M and UWP and all that fancy stuff).
I'm going to stick with my 925 for another couple of months (I just like the camera) and then will see how the smartphone market has developed. I just hope that now, as they realized they cannot/dont't want to provide W10M to all WP8 devices, they at least will roll out GDR2 to those devices. And I pray that they don't create another 7.8 like update with new colors and a new tile size... That was a joke and at that time felt just like another slap in my face.
I also have a S5 mini I use from time to time, which works great. Might as well switch to Android.
