You can't put a wide-angle lens on it

A couple months ago I bought a digital camera, a Canon SD10 Digital Elph 4 mp camera. The camera is awesome and really serves the purpose that I got it for. However, as I'm beginning to enjoy still images more and more I've realised that I would really like to get a camera with interchangeable lenses and the whole professional bit. This is more of a long-term goal, just thought I'd voice it now ;) Have a lovely day
