Well, the simplest way is just to just look at the N900 photo stream in Flickr: http://www.flickr.com/groups/1184299@N24/pool/ 81 members, so it's a really wide selection of photos from people taken with the N900, under different times and locations.
I wonder if all those reviewers are going to re-review the N900 in, say, a year, when new SSU-s, community fixes and brand new imaging oriented applications will be available ? They (and, well, most reviewers) reviewed it as they would a 'classic' phone, as a what-you-get-shipped-is-what-you're-stuck-with, and that's a paradigm the N900 does not fit.
