Given this is all nothing more than baseless navel-gazing, I suspect Dave is right that the next iteration of iPad is not going to turn the original on its head. Assuming the product cycle is more than a year (I’d eat my shoe if it wasn’t) much of the design work for iPad 2 was done before a consumer touched iPad 1. My guess is that iPad 3 is the one with the redesigned case.
If that is the case, I’m okay with it. I really like the design of the current iPad.
