Apple is proposing to implement a requirement for their store that apps must run in a sandbox. So system-level scripting environments can't be distributed through their store. This is a price I am prepared to accept.  

However, why didn't they do something to add value to their operating system, instead of adding a restriction on developers? Why not make virtualization part of the Mac OS X release. What an amazing thing that would be. I would then consider making all my web apps run in Mac OS X.  

Too many companies lack the creativity to see ways to expand the users' universe. Instead they are trying to shrink it. Since I'm a user in addition to being a developer, I find this depressing. It is depressing.  

Why do platform vendors always eventually pick fights with their users? 

How could this possibly work out well for them? (Or the rest of us.)
