Apple has finally gotten around to making the iPad camera connection kit available for pre-order and you can expect it to ship in late April. The kit supports all of the standard photo formats including JPEG and RAW and it sells for $29. Conveniently two connections are included:
The Camera Connector features a USB interface. Just plug it into the dock connector port on your iPad, then attach your digital camera or iPhone using a USB cable (not included).
Use the SD Card Reader to import photos directly from your camera's SD card. Connect it to your iPad, then insert your digital camera's SD card into the slot.
Why it's taken Apple this long to get this particular accessory up for pre-order is beyond us but never the less, it is now available for pre-order.
