Ars Technica’s Clint Ecker:
Apple should make it possible to not have to think about any of that stuff and just work on creating/consuming…it should be an option to not have to mess around with that stuff if you don’t care.
This idea likely predates the iPhone in 2007, but the work done in iOS to simplify adding and removing apps is a good place to look for inspiration. If they can do it for mobile devices, I see no reason not to adopt the same approach for the desktop.
I occasionally just want to be able to try an application, find out if it’s worth using, and if it’s not, get rid of it. As it stands now, that’s not as easy as it could be in OS X. Few people have the time (or inclination) to mess around with the file system on this level, and if they do, there’s always a chance that something could blow up.
3rd-party developers have stepped up to offer an alternative, but they really shouldn’t have to, not for a basic feature that is missing after almost 10 years. The structure is already in place for this (from a UI perspective), they just need to make it happen.
