Nadella sees this as the beginning of the post PC era
We're not big fans of the term "post PC era" because it implies that PCs are dead. However, it depends on the context and what you're describing. Certainly it's true that PCs are evolving -- mobile form factors are trendy right now, including lightweight notebooks, 2-in-1 hybrid devices, tablet PCs, and even smartphones. That said, if you were to sit down with Microsoft CEO Satya Nadella, he'd tell you we're entering the post-post PC era.
"I think we're at the very beginning of what I describe as the post-post PC era," Nadella said at Re/Code's Code Conference, InformationWeekreports. What he means by that is we're in an era where highly personalized digital experiences are more important than the very devices themselves.
To give an example of this, he brought up Skype Translator, a Skype app that offers near real-time translation of speech so that users from two different parts of the world who speak different languages can communicate with each other. This is the type of thing that offers a personalized experience, whether you're using a smartphone, notebook, or some other device.
In the end, it's just a matter of semantics. We tend to like Lenovo's perspective on things, which is that we're living in a PC Plus world rather than a post PC era.
