I'm sad to see the lumia name go. Mainly because I think that the surface phone is going to represent a whole new design philosophy which I'm probably not going to like.
The lumia line represents in my mind hardware excellence. They got a lot of things right in a phone, at a time just when the rest of the industry had more or less settled into a churn; releasing phones which addressed a few specification points, and did almost nothing else. Software is a different issue, and that's unfortunately where attention was necessary, yet Nokia were powerless in addressing.
I'm not holding my breath, but I really hope that something changes this year or next year. I really don't want to return to android, but I just get the feeling that there's nothing really left for Windows. It needs some sort of killer app, but you can almost guarantee that it will just be reverse engineered and moved to all the other platforms (like how they made a big deal with google translate doing camera translations, meanwhile bing was doing that a lot earlier). Either that or something to compel developers to support the platform. Everything else, I don't think is going to make or break the platform, specifically newer hardware.
I just hope that MS figures out how to gain some traction.
