I disagree with TS statement.
Firstly, even in the past, there are those whom don't know much about photography but still bought a SLR and learn from there. Just that internet was not prevalent then it does give a perception that SLR owners knows what they are doing. (what image quality can you tell from a 4R print?) Also with forums such as CS, the benchmark of quality photographs is raised quite significantly.
Secondly, the want/need for DSLR is different when compared to flim cams. In the digital world, you need to consider image quality from the different sized sensors and they differs pretty significantly from P&S to DSLRs.
