Mmyeah, it depends I guess. I for one never take images, and when I do, I disable the flash because it makes the images look horribly white and it annoys everyone else.
I believe Nokia phones make decent photos, even in poor-lit rooms, so I'll have to see. I think it's a perfect phone to try out WP8 since other phones are directly double the price. I would still really consider it, even though it has no flash.
I'm mostly looking forward to the default Nokia apps. They should be top-notch.
Anyway, I should get it between now and Monday, so if you're interested I could share my impressions and/or take some pictures or whatever.
