I'm seriously considering it as an early upgrade. I sold my Lumia 800 about 2 months ago to buy a 620 and nice as it is, I would rather have had bought the 920 at the time, just couldn't afford it. While I think the 925 is slightly less visually appealing, it being thinner and lighter and with a better camera (the main selling point for me) is a big plus.
I'll have to wait and see what the tariffs are, but I'm willing to put up to ?100 down up front if I can get a contract for under ?30 per month. Anything more than that, up front or per month and I'll just stick with what I've got.
