I've been reading this thread for a few days and thought I'd de-lurk.
I originally ordered the Lumia in black (boring I know but I wanted a matte colour) from EE on their 12 month, 51 quid contract. However for goodness knows what reason I failed their credit check - the highest they would offer me was 46 quid per month, even though I offered to pay the entire contract price up front. Madness. So I cancelled.
Since then, I decided that I was happyish paying about 37 quid per month for a smartphone, as this is what I paid for an iphone with a higher upfront cost. With the P4U quidco cashback, this means that I effectively pay 21 quid over two years for 4G on the 41 quid 24 month contract. Not a great total cost over two years, but one I can probably live with.
As for the weight, I prefer heavier phones - I found the iphone a bit light after an Omnia HD, and having played briefly with a (sadly turned off) demo model, I think I'm going to like the 920.
I've never seen a launch handled quite this badly though ...
