I also proudly own a 400D. It's cheap and cheerful for an SLR. I personally am not a photographer much and only got one because... I don't know I needed something to ask for for passing my gcses.
Everyone always mention the small grip and size as a disadvantage but I've found it to my advantage considering I'm a 5ft tall girl with tiny hands anything bigger would be harder to hold.
I was just wondering how much exactly did you get your camera for and what did it come with?
I think mine was about ?360. And it came with an extra battery, massive re-adjusable camera stand, some UV lense protector add on thing, 1GB memory card and a black camera bag.
And yeah the lense it comes with doesnt produce as good as quality as the 18mm-55mm that the Nikons come with as my mate's picture quality are evidentally a bit better.. Although, it is most likely because I can't take good pictures.
