(a) i'm thinking home usage. An 8 core machine with 6GB RAM is plenty - plug in a keyboard, mouse and screen, who needs a mac mini? OTG and/or a hard disk attached to my wifi router is all the local storage I'd need, let alone the cloud.

(c) If Google pulls off seamless integration of Android apps on a Chrome OS tablet then the rumoured ARM Macbook may have users wondering why they can't run their favourite iOS apps too.

But that's just me, I guess, and my wants.
