Re: level one Apple Care
They'd have to partner with someone for 24 hr on-site service, or limit it only to areas where an Apple store is somewhere in the vicinity. There are plenty of places further than a day's drive from the nearest Apple store, since they don't tend to put them in rural areas of the US (to say nothing of the ROW)
I suppose they could offer next day shipping for advanced replacement, but that's gonna be pricey. Be cheaper for a corporate customer to just keep a few spares on hand and allow repairs to proceed the slow way if they don't have an Apple Store in town.
