People who placed pre-orders for the iPad after Saturday, March 27, are finding that they will have to wait a few weeks beyond the April 3 launch date to receive their devices. The shipping date for those pre-orders is now April 12. These dates apply to the first wave of iPads that will hit the market — the WiFi-only units. It appears that consumers who ordered the 3G + WiFi iPads are still on track to receive their devices in late April.
