You'll get pretty much the same replies as everyone who asks that question.
Go to your local camera shop, Curry's etc and hold both the Canon and Nikons. I've no idea on the Nikon models as I'm a Canon guy. From what I've read on here though, lenses are a bit more tricky with Nikon as some need the focus motor built in (although in sure someone on here will be able to explain better than me)
Even try the Sony NEX range too. Very good cameras from what I've seen.
The kit lens that you'd usually get would be OK to start with with, then look at a 10-20 sigma for city and landscapes and a 50mm 1.8 which is good for people shots (although I'm looking at 30mm primes to replace the 50mm)
