What I meant was, as that is the only thread with photos you have posted in a while, what is it about your current camera that you find lacking and you are limited by your gear? No use upgrading to take better photos, cause 90% of photography is the person behind the lens. My post was to make you think about WHY you want to upgrade, and if it is to 'take better photos', then you are upgrading for the wrong reason.
If you can tell me limitations of your gear that are restricting your current photography experience, then you are giving me reasons that upgrading might be worth considering.
So based on your reply, it seems you have considered this and know that the 400D is limiting your photography, and therefore, yes you should upgrade. I just wanted to make sure you were not upgrading just hoping that a new camera would take better photos, without understanding why
