I can't get Chrome to work reliably on OS-X or iOS. The overwhelming majority of "Spinning Beach Balls of Death" I got on my old MacMini and on my new MacBookPro were from Chrome. On iOS it just randomly crashes, and would occasionally munge up my bookmarks. (On top of that, Google's logic for checking if DNS is working correctly caused my ISP's DNS servers to treat me as an attacker and start ignoring me, so I would lose their DNS for some time after I started using Chrome. I eventually switched to another DNS server at router-level, but it took a while to find the cause.)

But I agree with you on the rest - these are not issues the majority of users face, and I've seen none of them. [Edit: Few of them. I'm somewhat sympathetic to stance that Apple's software is lacking in some polish. And Preview after Lion has been /less than helpful/ for reviewing batches of images.]
