Sony 400 Disc Blu-ray changer we wondered what it must be like to try and navigate through 400 movies to find something to watch. Sony was quick to tout its award winning XrossMediaBar interface, but you really never know until you see it first hand. We stopped by Sony's booth at CEDIA and we have to say it's pretty sad. We can't even imagine paying that much for something that is frustrating. The fact is that one user interface design does not fit all, and while the XrossMediaBar works for many applications, it is hard to beat the good ol' tile view for browsing movies. The Sony representative giving the demo was quick to remind us that you can use another piece of equipment to browse your movies, which will in turn control the changer, but that's no excuse. The good news though is that the big guy did manage to change discs pretty fast.
