I think there's much enthusiasm for Blu-Ray, according to another research a vast majority of PS3 owners watch Blu-Ray movies.
Of course entry pricing plays a critical role like was the case with regard to the mass adoption of VHS and DVD, I don't think there's anything surprising there.
Compared to VHS and DVD, Blu-Ray without the PS3 probably would have had a harder struggle for adoption as the migration of SDTV to HDTV is still taking place on a massive scale, HDTV penetration is critical for Blu-Ray penetration.
With regard to Sony's media-related "misadventures", I think that the more educated consumer recognizes that Sony's success stories far outweigh any past failures (PS1, PS2, 3.5 inch diskettes, Compact Disc (CD), collaboration for DVD with Toshiba/Philips, etc, etc.
In general Sony has an outstanding reputation for their high quality consumer electronics, no doubt about that. I think in general they are very much at the forefront in terms of general reputation and achievements, ahead of other leading edge companies like Philips, Sam Sung, Panasonic, etc.
