Mainly just want to document, so travel, portraits that sort of stuff. Also printing the odd picture - nothing huge.
Also - to add I like the idea of wifi connectivity.
Pretty much anything will work for you in that respect. Decide if you want interchanges lenses or not. If you want interchangeable lenses, weigh up the cost of them.
Decide how compact you need it and if you need viewfinder as well as a screen. Try a few out in John Lewis, Jessops etc.
What are you taking photos of ? and what do you want to do with the images ?
