I actually had the reverse chronology. I discovered how using ClickToFlash gave me significantly better battery life on my MBP, along with faster page loads and zero mysterious pinwheels. ClickToFlash has a better price-performance ratio than upgrading to an SSD – and I love my SSD.
So when I got an iPad, I was especially mystified at why anyone should complain about this garbage being missing.
edit: Useful links.
