Well it arrived last week and so far I've been nothing but impressed - 10/10!
I've also fairly recently moved home and thus my old commute to Canon Street is no more! I now (if I walk) get to go past tourist attractions such as St Pauls, Blackfriars Bridge and down towards Waterloo (where the internationally famous London Eye stands tall). During this walk I took some photos with my 'old' k800i and was reasonably impressed with them (factoring in that it is primarily a phone). After getting my new k850i I decided to walk the route again and take some more shots - a like-for-like comparison!
