Actually, you're right--we weren't debating that. Until you said that an iPad has an inability to create content, that is. Try to keep up...with your own contribution to the discussion.
Your analogy completely fails, btw. MBA:iPad =/= Canvas:etch-a-sketch. Sure, someone might be able to create art on an etch-a-sketch, but it will be a proof of concept experience--a, look at my talent, I have created this amazing thing in a very difficult medium. There are people who prefer and in fact do greater creative work on the iPad.
Just because YOU don't find that to be true doesn't make it false for everyone who does.
TBH, I don't know if it will be true for me, either. The new iPad will be my first tablet. I have a feeling that I will adore it for writing (especially once L&L release the Scrivener app). However, while I can certainly imagine ways that it will interface with my photography workflow, I doubt that I'll be able to do anything other than simple post on the iPad. The hardware and software just isn't there yet.
Of course, the MBA isn't quite powerful enough for what I throw out in a typical editing session either. That's why I have my Mac Pro and MBP.
