Looks nice. But that was never Nokia's problem. They always made really nice looking phones with great hardware. But their OS always let them down.
With Windows streamlining their OS across their PC, tablet, mobile and Xbox range we might see a new standard in how we use electronics. But its always going to be a catchup and the second the Lumia sale numbers dont look good then I can see Nokia racing to get into Andorids bed
Doubt it, I'd say you'd see MS buying them and going down the route of Apple. Thing is, MS have invested so much in their new UI they can't not have a phone presence it would completely fuck their whole plan up.
I just got a Lumia 800 for my work phone and I must say it's an absolute pleasure to use, I've previously had a HD7 but fucked it up (dropped it in the sea) and have been using Android phones since, I can honestly say I will never purchase and Android phone whilst WP exists, it's just inferior in terms of usability, aesthetics and general feel.
There's over 100,000 apps in the ecosystem currently (in under 2 years) and with Windows 8 and WP8 using the same kernal it will be a lot easier for developers to convert their apps across. Personally I don't use a lot of apps but I can see it being a sticking point for some, but these tend to be power users more than anything.
I honestly urge anyone who hasn't used WP to give it a go for a month and tell me it's not fantastic to use, I'd even say it's simpler than IOS to operate, and with the latest iteration released next month on new hardware it's only going to get better.
