Don't want to dampen the excitment on the camera connection kit but:
1) Wouldn't it be cheaper to just buy more SD cards for your camera? When you are full, use the next one. I have an 8GB card now... if that was full (and that would take a lot of photos and video- not sure how you could fill it up) , and I saved it to my iPad, it would use up a LOT of space on the iPad. Unless you had a 64GB iPad, again, isn't it better to get a couple of SD cards?
2) OK, I get it- so what if you want to email the photos? Well, you don't really have iPhoto on iPad I don't think. Will it send photos in the "emailable" smaller sizes? Prob yes. But can you edit the photos in any way like with iPhoto? That is what I really want..... Crop, touchup, annotate, redeye, enhance, effects..... Unless it does that, it isn't that great.
Nobody (well almost) is buying this just to store the photos on the iPad. The idea is to use the power of iPad to use advanced media features on it. There'll be Photoshop for iPad, PhotoGene, ColorOfTouch and so many photography apps will be porting to iPad. The Photos app will be able to email the photos in any size or you can use other applications to upload to flickr and facebook.
Imagine photographers who bring their laptops to do simple editing before previewing them to the clients, with this camera kit, they'll just directly import it, do their stuff, and preview it to their clients within seconds.
