Yes probably. And in reality if you look at laptops > $1k it's not even close, Apple has 90% of that market. What that says to me though is that most people care more about cost than aesthetics. The point being that aesthetics isn't really the trump card that a lot of people think it is.
I think we have to bucket buyers into different groups. For one large group I think it is the dominant factor. I think the word "aesthetics" maybe be a bit of a misnomer. It's more than just physical appearance. There's a clean elegance to almost all aspects of the device including the software.
The tablets will be a good test, so far the android tablets aren't a lot cheaper than the ipad. We'll see how they do.
