depends on your personality... go in and try/demo them both.
Nikon is geared towards the elegant. simple, good menu's, intuitive...
Cannon is geared towards the engineer. lots of things to play and tinker with..
kinda like Mac vs. PC ... except that both Nikon and Cannon are equally amazing at what they do.
dont think so
canon isnt complicated to me
all cameras have a learning curve
but for a total newbie to the dslr scene 2-3 years ago...Canon wasnt that hard to learn
i'd say go for that xsi deal
sell the zoom lense and get a faster prime lense
