The New York Times reports that Apple announced it had sold one million units of its iPads as of Friday last week, and that demand outstrips supply. Apple also said there were now 5,000 iPad-specific apps available for the device.
Macworld also published a first look review at Apple's $29 iPad Camera Connection Kit, which confirms that the device can upload and store RAW images (nef and cr2) but there isn't a way to edit these images as yet. The iPad generates JPEG versions of these files, and it's these that iPad users can email, create sideshows with, and edit with 3rd party applications.
I am not convinced this device is an accessory can serve photographers in its current iteration. Some photographers (mostly studio) perhaps will use it as a viewer during photo shoots, and wedding photographers are thinking of buying them instead of wedding albums to send to their clients...while others will use it instead of portfolio books to showcase their work to important clients.
Other than that, the bottom line is let's wait and see....there's no just meat on these bones for me.
