Rootkit. Copyright lawsuits against individuals. They welched on the warranty for my Sony Vaio laptop and wasted a ton of my time. Someone got me to buy a PS4, and I hate it and find it to be user-hostile. Basically, any time I have some experience with Sony, it is a bad experience. YMMV.
edit: can someone please tell me why ps4s have to do some lengthy time-wasting fsck-like this every time they lose power? Did no one at Sony know what journaling filesystems were?
