And you have hit the nail on the head.... You can take any current DSLR...Nikon, Sony, Canon, whatever.... And take wonderful pictures... The differences are minimal to the average user.
This gets brought up in these discussions regularly, but it's not really saying anything at all, is it?
Every camera technological debate thread can end with "all cameras take nice pictures".
But a site such as this operates within a tech-context, and tech thrives on incremental improvement. So saying "the difference is minimal" over an over in every thread along with other platitudes dilutes the discussion.
The particular tech matters though, particularly when advising on buying options to comparatively uninformed people - HiFi is dead to most people as an important thing to argue over, while CPU or videocards can be shown to have quite large differences for instance.
For most people, digital camera advances are getting smaller and smaller over time, particularly with more automated editting and the main display format being screens rather than print. Making it clear that the practical difference means you cant lose can be rather helpful for people anxious about whether they have to worry too much.
