Choice. There I said it. Who gives a crap if you'll never use Flash. Who gives a crap if your neighbor does? What's wrong with giving the user that option? God forbid you hit a Flash site, because we all know there aren't many out there *sarcastic*, wouldn't it be at least convenient to have it? All douchey fanboy crap aside.. wouldn't it?
I do happen to think for myself, as can you. How much plainer can Apple make it? They choose not to support Flash. It's not a secret. A iPad is not essential to human life, it's a useful tool for those people whose needs it meets. Clearly not 100% of the population. You have Android options, the Playbook and even an "Adam" tablet.
You're not going to force Apple to give you 100% of everything you want and it can be argued that the Xoom, Playbook and others don't meet 100% of all users' expectations.
And I don't need statistical analysis to demonstrate that Apple has sold a buttload of iPads despite all these supposed shortcomings. It's just not that important for most users.
