I think you are underestimating how hard it is to implement proper copy/paste on a touchscreen device with no keyboard. I must say that I find Apple's implementation very intuitive and easy to use.
No, I'm not saying that it doesn't have certain considerations necessary to make it work well. We can't even get proper clipboard support in Ubuntu these days. So I'm not saying it's really that simple.
Yes, I am saying it's not a big feature. Again, it's like VW coming out with a new Jetta, and one of the specs they touted was "Now with tires!!!"
