A concern. Given how Apple don't like to drop a product from future enhancements till it's quite a few years old. Is there a danger than iPad2 will have to be restrained a bit due to iPad1 ? They won't want to have two models on the market for developers to have to write for, and they won't want a lot of iPad2 apps coming out that iPad1 owners can't run. To me, this can only mean one thing. Without being able to start with a clean sheet of paper for the next model, it can't be enhanced very much without causing issues. Perhaps not till iPad4 might iPad1 be considered too old to worry about too much. Thoughts?
