To me, Sony always has been the king when it comes to electronic design. They just have that special people extremely talented to make products that looks sophisticated, elegant yet fully functional.
Back in the days (80's and earlier) everything from them were top notch, after that only their premium line had that touch, the rest were still great, but not at "Holy crap!!!" level.
I think one of the reasons why you see threads like this one is because Sony used to be the best at pretty much everything. Sony was the one pushing the technology to levels that pretty much none other company was (Matsushita being the exception), so I think they still deserve the praise they get.
Having said that, you can't live looking at the past and it's undeniable Sony became sloppy at making new tech. Also, they lacked the vision to anticipate where the world tech were going. I mean... as some other have pointed out in the past, Sony should have been the company that created the iPod and latter... the iPhone. That speaks a lot of the lack of direction within the company.
I really wish them the best cause I think they still have a lot great minds there with an impressive amount of patents under their belt, but I don't know if they will turn around the situation. Their financial status it's not the best, also... the competition with other manufactures is tougher than ever (decades ago it was only other japanese brands, today it's also Korean).
Just to finish, some of my favs designs:
Man, that last one looks so badass!!!!
