I live in the USA and left Windows Phone, but not because I don't love it.
My Lumia 920 died.... I went to AT&T and they had no phones that would replace it. I didn't want to spend more...
I don't think it's ridiculous. This (as I know you know) isn't an RTM product. Your mileage may vary with Windows 10 in it's current release.
I'd guess that they'd strip it out but the Lumia 830 has a removable back cover that you can add a Qi wireless charging cover onto at a later date.
Really all this comes down to is.
Do I wait for a 1020 replacement, I do like what I see with Denim.
Or do I go with the iPhone 6 which has more apps and great support from everyone...
I know you are saying that more phones will come but are they coming this year, or do you not know?
