Apple doesn't like to charge my iPad "Air" as quickly as it can with a Monoprice charger. It even puts a nastygram on the screen when you connect the iPad to the charger.

I'm assuming that they will do this with USB-C.

That does trouble me a bit, but if they stick to the spec (and I assume the retina Macbook hasn't deviated in any way to suggest they will for future models), then I see no reason not to remain tentatively optimistic.

I don't see any reason to go off spec given that they should be able to go up to 100W, but I may be wrong. Or Apple might come up with some hazy excuse for why the existing standard was no good. It'd be a real shame, though.
