And Microsoft got a ton shit for it pre launch. When people are looking forward to a new generation, they want to see new stuff, and Sony gave them that.
Then you get the console home and a few days later it's not new anymore, a new coat of paint ain't all it's cracked up to be.
FWIW I prefer Xbox's direction here and the fact that we can watch the OS evolve over this new generation, that's seems a lot better than simply saying "oh that's different" for five minutes on day one and then wondering why stuff is backwards and standard features have disappeared.
