I guess upgrading a 950 to a 970 is a no brainer. Especialy if I can get over $600 on E-bay for my old 950.
With the exception of the 100 MHz video bandwith and DSP Conversion, I don't find the other changes that valuable. When I use headphones it will be hooked to my I-pod
I hated the green button anyway.
