I honestly don't think "neo" invokes thoughts of "new" to most people (despite the Greek etymology, of which I'm well aware).
It's a subtle distinction, but I think the general connotation is more like "hyper-modern" or "reinvention/reinterpretation."
People won't see "MacBook Neo" and think "oh there's just a new MacBook."
I will be waiting for the MacBook Trinity.
