The cameras provided are just fine
The iPad2 will not replace my Canon DSLRs, Leica, and Sony DSLR gear and the dozen lenses I have to support them. Can you just imagine running around photographing sunsets with an iPad? The iPad is not a camera and the cameras provided are solely for video teleconferencing use.
As to 128 gig storage, what on earth for? I have 600 photos, ten movies, nine books, many magazines, 3,000 songs,and a ton of apps on my 64 gig iPad1 and barely use 31 of it's available 64 gig storage space.
Just my two cent worth. And it is my two cents.
