What is the best camera you can buy for money or maybe the camera you have in mind has not been invented yet If that is the case what do you think will be photography like in the future?

In my case the best camera is always the one which you just happen to have with you when you want to shoot a picture. This makes my mobile phone the best camera but the quality is poor. So my ideal camera would be the one within a mobile phone but as good and fast as an SLR.
