I bought this kit when I bought my ipad this week and I've found it very useful.
I was unsure as to whether to buy it at first as I had heard that the 4.2 update had reduced power to the usb and some accessories no longer worked because of this.
However,I'm glad I did as I've had no problem importing photos from my SD cards and I even thought I'd try using my wireless usb Acer Revo keyboard and it worked.
I paid £26 for mine from Currys and thought the My Memory price was quite good at £20.99 with free postage.
With the iPad Camera Connection Kit, it's incredibly easy to download photos from your digital camera to your iPad so you can view them on the gorgeous iPad display and share them with family and friends.
The kit includes two connectors, each with a different interface:
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). iPhone 3G is not supported.
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.
After you make the connection, your iPad automatically opens the Photos app, which lets you choose which pictures to import, then organizes the selected photos into albums. When you sync iPad to your PC or Mac, the photos on your iPad are added to your computer's photo library.
iPad and the Camera Connection Kit support standard photo formats, including JPEG and RAW.
