Sorry if this was discussed before. For those of us who pre-ordered for home delivery, the order receipt clearly states delivery will happen on 4/3. What's interesting about this to me is this is on a Saturday, a smart move by Apple to ease the pressure on whatever delivery service(s) they choose to utilize.
What's also interesting is this is the Saturday on Easter weekend, not a big deal considering both the major carriers (FedEx and UPS) don't observe Easter holidays (i.e. they don't take off Good Friday or Easter Monday according to their calendars published online.)
Of course, I'm expecting the iPads will be drop shipped separately from the accessories, so I'm not expecting to see them (accessories) Saturday the 3rd.
