> In other words, for the MM concept to take off ... The "MM concept" has already taken off: in the form of billions of smartphones. Its gestures and scrolling behavior are most natural for someone coming in from smartphones/tablets to personal computers, and mostly identical to Apple trackpad gestures in any case. Most software does not require any special development to handle Magic Mouse gestures; they are mapped to common events like zoom/pan by the OS API, which are shared with the MacBook trackpad and thus already supported by all well-written apps. Developers DO need to take the MM into account to provide extra, hand-tuned support for its features. The apps you described and games are where its advantages fall apart the most noticeably. Though, you may be able to use BetterTouchTool to "hack" MM support into third-party apps.
