While it would be nice to have an option, I don't think it's an issue. You get used to the grid/page and don't really mind the icon or text after you're familiar with your device. Even if Apple supplied many high quality icons to choose from it might still look cheap. Even the default Mac OS user icons are cheap looking.
PS: With ICS Android finally has drag-and-drop and icon onto another to create a folder. I can't but think if that happened the other way around there would a dozen new posters on this forum signing up just to point out how Apple copied Google.
PPS: I also imagine if a volume rocker issue existed on the iPhone that it would cause a worldwide panic and would be front page news about how the greedy Apple rushed another product to market.
