I have always considered Apple Computer Inc. to be the Nazi's of the technology sector. It will be a boon to system security if only signed apps can be run since malware is not signed. However, I do not like the $99 entry fee for the pay to play model. This is why I stay clear of Apple. Microsoft does not have such restrictions, and Linux/Unix you can do whatever you want. Android recently introduced a new version of their development kit which is also $99, but is not as restrictive as Apple is as to what APIs you can use and such.
With that said, one must consider the target audience. Most people who buy Macs are not computer savvy. So changes like these will actually protect these users. However, it puts additional burdens on the developers because now more hoops have to be jumped through to install applications onto the system now.
Just my 2 cents.
