It makes sense that the air would be updated with a core m but still, its kind of a shame, I'm under the impression that core m is only good for chromebooks and tablets , and it's a seriously underpowered chip , am I exaggerating?
Let's see. Lenovo's Yoga 3 Pro with the Core M had issues while playing 1080p video, and had **** battery life, so I don't know.
I think Core M will be more then adequate for normal day-to-day computing, such as email, browsing, social media, office applications etc. Its targeted at an average user that does not do anything demanding with the computer. Of course, once you throw intensive applications at it, it will struggle. Its true that first review of Core M were not so stellar, but its most likely that Lenovo's less than exemplary engineering is to blame here.
