Yup, I got a Lumia 800 as a work phone last week – currently I also have a personal phone, too – iPhone 4. Initially, I found battery life terrible – but it’s got better recently, probably because I’m not endlessly mucking around with it. On 7.1 at the moment, by the way.
Apps? Flickr’s good. Weatherbug is also great, but I’ve not been able to tile it yet. Other than that, I’ve been swamped in the run-up to Chrimbo and haven’t had a chance to muck around with apps yet.
Liking the aggregation of content into ‘me’ and ‘contacts’ works well, makes sense to do it like this rather than in separate apps.
Camera’s smashing, generally very responsive interface for the phone. Display is beautiful.
