Anyone worried about Apple post-Jobs should do a little research on the Apple University -- a program Steve started after he was diagnosed with cancer that is internal to Apple and whose responsibilities include training employees on the proper Apple culture that Steve fostered -- the design emphasis on simplicity and the unrelenting passion for perfection, etc. It was a brilliant maneuver made by Jobs to ensure that his mindset, management style, and key areas of focus survived him.
Beyond that, as sam mentioned, he left with a product pipeline for the next 4 years -- which is more than a stable groundwork for Cook and the remainder of the Apple staff to build off of for the continued success of Apple.
I think that (especially given the immense turnaround of Apple in the late 1990s) the company understands that the reason for their success was largely due to Jobs's mindset and his unwavering dedication to perfection and simplicity -- with any luck they will continue to epitomize those traits going forward.
I never use the iPad for the camera, that is what I have a DSLR for (but in a pinch it can work). I use it when I am not wanting to be tied down to a desktop or a laptop. Who in the right mind only uses it for a camera though, thats what I want to know. :)
I'm getting a first generation iPad from my cousin once she upgrades to the iPad 2. I will be just as happy to have that one as I would getting the 2. I'm also not planning on using the camera anyway.
