I'm not really being jaelous of the new Lumias personally as a 920 owner. While I loved the aluminium design of N8 (thus would likely love the aluminium Lumia), but there are tradeoffs to the lighter devices, such that I'm not necessarily ready to make. Also I do feel that 130g or so is too light for a 4,5"+ device that easily makes it feel a bit toyish for me. The weight of the 920 never bothered me, quite the contrary, I love that it's heavier.
The 925 is what would be available to me in Finland, but while I would suffice with 16gb of internal memory, I rather have the 32gb of the 920, cos I'm in the for the long haul with this one and I dont want to delete or move stuff around constantly. The other thing is the AMOLED-screen. I think it works pretty well with WP8, cos of there's so much black in the UI most of the time. However, the IPS on 920 is absolutely frigging gorgeous. That said, AMOLED has the benefit of the Nokia Glance-like features not sucking all of your battery and generally speaking the main OS view using less power due to turned off pixels.
If I didnt have my 920 right now, I have to say that I might opt for the 925 though. But it would be very tight.. cos I think 920 has a better balance for me, but in my books the aluminium design gets quite a bit of score from me
But I'm really happy with my 920 regardless. Grass is always a tad greener in some aspects on the other side, but it's always a trade off of something.
