Applications you wish were ported from other platforms

While waiting for Rx-51 and friends, it could be useful to list all those apps from other platforms (Symbian, Palm, Iphone, Java etc.) you can't live without, and you wish were ported on your new maemo convergence device.

Please list here, also including the operating system, the developer's site if you know it, and a brief summary of their functionality.

Shazam Id - Symbian, Iphone, Blackberry, Android - http://www.shazam.com - listens to music and recognizes author and title.

Audials mobile - Symbian - http://audials.com - searches for author or genre, leeches mp3 files from online social radios.
