Sony has been beating itself up over its recent performances, using a CES presentation to admit that it "forgot" how to get people excited about its products.

"We used to make people say wow all the time" said the self-abusing voiceover at the beginning of its CES press conference late last night. "Our unique combination of artists and engineers set out to create a surprise everyday. We forgot the power of that for a while."

With quite a few people saying "wow" over the new quad-core Xperia Z phone Sony showed off yesterday, it looks like it could well be back on some sort of desirable tech-making form. [Techradar]
