My guess is that the Lenovo Chromebooks will be aimed at the consumer market. Cloud is taking over the market. Doesn't matter if you have a public or private cloud. Mobile apps are becoming more powerful/featured. If the feature set is lacking, you simple remote into your personal computer for a fully featured program.
High powered mobile devices are pretty much used by business/commercial users nowadays. People who need fully functioning machines on the go or have high security requirements that mobile devices do not provide.
