The trouble is, yes, most people only use 10 or 20 apps, but they are unlikely to be the same 10 or 20 for everyone. If you trim a few apps away, a few people will complain, and the more you trim away the more people will feel their phone is being crippled. We've seen that with the iPhone, people praised the interface for simplicity but complained that it lacked important features. If Apple had included all the functionality of S60, the iPhone might not have seemed so easy to use.
What's needed is a way to keep all those 60 or more apps, but only display the 10 or 20 that each person actually uses. In other words, have a simple menu at the front which would be the equivalent of the dashboard of a car, and then the complex but fully-loaded menu as the equivalent of the engine. Ordinary users can stick to the dashboard, while power users could dip into all the options and features to tune them to their liking.
Desktop computer OSes such as Windows have been doing this for over ten years now, displaying automatic shortcuts to the most commonly used files and apps through the Start menu or equivalent. This same system ought to be available on the standby screen of all phones.
The standby screen is actually quite useful if you know how to customise it, but that customisation option is buried a bit too deeply in the settings menus so most people never seem to find it. Consequently, most people still have to go into the main menu screen.
If the choice of icons in active standby was automated and constantly updated in an intelligent way, the standby screen would turn into what would effectively be the main menu for most people, as it would have those 10 or 20 apps which they do use regularly.
"even when you get to the right dialog it's not even sorted in alphabetical order;"
Which language though? Alphabetical order would mean having icons in completely different orders in different languages. That could make testing a UI for speed and ease of use a bit of a nightmare...
"Well, maybe next time something like the N95 comes out with its really nice-looking "media" menu, reviewers and early adopters shouldn't go around hardly mentioning it and giving the impression: "don't use it, it's slow, the media key serves no useful function, it's just a gimmick", and so on."
I agree, people can't have it both ways. They can't simultaneously have a small number of essential icons and a full-on every-option-displayed menu. The "carousel" menu ought to be seen as a set of shortcuts, which is what it is. It's no worse than the bookmarks of a web browser.
