I had never considered Nokia as my choice of brand. I only went to Nokia because of WP8. I currently still have a Samsung Focus with WP7 and I love it very much. It's light and durable. As a matter of fact I'm currently using the Focus instead of my Lumia 820 because the very first time I dropped the Lumia 820 the digitizer broke. So I'm not as impressed with the Nokia as I am with the Samsung Focus, it takes a licking and it keeps on ticking. Not that I like to drop test my electronics, but it happens and I have dropped my Samsung Focus many times and I never had an issue with it. I'm currently waiting for parts to replace the Digitizer in my Lumia. So I was just last night wondering if I could find a Samsung Focus with WP8.
So the Nokia brand is not why I have a Lumia 820. I have a Nokia because it has Windows Phone 8. So Nokia had my business because of WP otherwise I would have never considered Nokia as a brand of choice. So there are some of those of us that now have a Nokia because of Windows and if Windows Phone goes to a different brand I will follow Windows Phone to that other brand. Thinking of how much I enjoyed the Focus, It would be nice if Samsung also had the Windows Phone 8 available in one of their models. Just my thoughts.
I'm not bashing Nokia or promoting Samsung...I'm just expressing my experience with both of those brands.
