Your friend is correct - ALL cameras are obsolete shortly after their introduction. If you wait for the next best model you'll never get there.
Your question is very difficult for anyone but you to answer because much depends on how you are going to use the camera and the final resulting images. Basically, when you purchase a (D)SLR body you are buying into a camera system - as you grow in your photography skills and needs the system is expandable to meet your needs.
Many beginners will start with a point and shoot camera and find they like photography and want to learn more. At that point they usually move up to a (D)SLR system. Others will never find the need for more that a basic P/S camera.
I know this does not help but you may just have to "jump in" and try for yourself.
