I agree, to be honest I'm just desperate for a small take-everywhere laptop for development. 😉 (and I find even 13" too large for that scenario). Even the base Macbook Air is out of reach for many, so if Apple pulls off an entry level laptop that's closer to the base Mac mini in price, it will sway a lot of people I know.[developers are] not the target audience (I believe).
The target audience, I think, would be people „on the fence“ about whether they‘ll buy a MacBook or a Windows machine. Or a notebook at all.
