I notice that you are quick to respond to people who don't show sufficient deference to your opinions, but you have not yet responded to my substantive arguments. In what way is it a negative thing for me to extend the functionality of my phone to make better use of its capabilities? Using apps from Cydia I have been able to store, manage, and edit files on my iPhone; use my phone as a mobile terminal as part of my job as a sysadmin; multitask; switch between open tasks; view, edit, and listen to files in formats not supported by Apple or by any App store app; view information about my phone; and manage my phone's memory -- all of which are things that Apple refuses to allow me to do through any native or App store application. None of these thing affects Apple's bottom line in any way (after all, Apple has already refused to allow these apps in its App store), and none of them negatively impacts the lovely user interface Apple has designed for me. So how again is this a problem?
