When PS3 came out, it was excellent. It was an adult-oriented standalone console that worked well as a media center and it was also really well designed. It was true to the spirit of old Sony electronics - a self-sufficient device with a polished interface that matched its function. Sure it had a hook up to the Internet and PSN, but it was secondary. But then they started "improving" things. First, you got promo ads in the corner of the home screen. Never asked for a permission, no way to turn them off, even by disabling the network connection. So my device was little bit less mine. Then they started pushing "selected apps"- Netflix-Shmetflix and what not. Again, without asking, just because it was good for me, and, again, the device became even less mine. At the same time they increased the font size and replaced that beautiful Navier-Stokes visualization of a loading indicator with some generic spinner clock thingy. Sprinkled some other crap over the UI.
Just now imagine your old Sony cassette deck deciding to show you ads for new Justin Bieber album and offering to share shit on Facebook. That's PS3 now. So it's hardly surprising that I have no hope and zero expectations that PS4 will be anything else but a disappointment.
