I can't believe ios 4 still isn't available on the ipad! that is ridiculous! it should have launched with ios 4. but whatever I guess I should just be glad that it is here now
My money is on timing and unexpected capabilities. The timing concerns the introduction of a new, fresh OS, right when competitors are are busy responding to old OS functionality. Then if Apple offers some completely unexpected capabilities, say something wildly radical like hard disk connectivity to iPad (not gonna happen.), Apple delivers a one-two punch. I have no idea what unexpected capability they might cook up, but if they do introduce something unexpected, bam! It would make it more difficult for competitors to catch up.
