^^^ This.
I've had a few digital cameras over the years but was always irritated by their lack of instant shot, as you'd push the button, the camera would auto-focus, then it would stop and have a cup of tea, then a biscuit, then finally it might get round to taking the actual photo eventually. Not a huge issue if you're only ever taking shots of still things, but for anything moving they're utterly useless and you get by on luck alone. My missus has one still and it's fine for her but it does my head in, and for that reason alone my DSLR purchase has more than justified itself over the last few years.

at the same event (goodwood) me and my mum are taking pics.
i have the DSLR Canon EOS 500D and my mum a top range Panasonic Lumix.
we were taking the roughly the same pics and my mum was struggling to get just one car in view.
i have loads of pics on the day and the quality is so much better that her camera.
the Canon was about 500 and the Lumix was about 250-300. however was well worth the extra money.
