For us, smartphones like the iPhone and Nokia Lumia are just too expensive. So for the time being, we remain users of Nokia dumb phones. But here is the crazy part. The Nokia dumb phones we had years ago (model 3315) were better all round compared to their current offerings, except for their reduced physical size and reduced price. Thus over the period of about a decade, Nokia’s dumb phones have not offered us any significant improvement. Simple, Nokia has missed the mark with us.
As for the Lumia, it is a nice looking device, but the buttons feel cheap. I picked on up, hoping to be wowed, and almost immediately put it down again. At around $800, I would have expected much better.
