Neo is wily popular, but don't expect it to generate significant profits for Apple (disclosure I'm a AAPL shareholder). I assume the profit/profit margin on Neo is paper thin.
2) They will generate more profits than the hardware itself. You're not counting services and ecosystem. Now you got a new matching iPhone to go with your Neo, and an iWatch, an iPad, an iPencil...
I think this may actually be the first real Halo product they have that will do this for Mac, because it is a Mac.
