I didn't find a great deal of stuff on the App Store that I was interested in, but I _was_ interested to see that Apple are advertising that any App on the App Store can be redownloaded as often as you like and installed on as many Macs as you like. That means that the licenses for some programs, such as Omnifocus and Delicious Library 2, have effectively become much more permissive as a result of being posted to the App Store. Both these programs have activation DRM in their non-app-store versions which allows them to run on only one machine at a time. Presumably the App Store versions do not have this restriction. (This doesn't seem to be related to whether App Store recognises the non-app-store version as an installation or not, by the way; it recognises the DRMed Delicious Library 2 but not the DRMed OmniFocus.) I've contacted the companies that make these programs to ask if the more permissive license terms will be available to buyers who purchased by means other than the App Store. I think other people from this forum should, too, if you have Apps in that class. If this can finally bring an end to Family Packs, which are a Mac-only thing that I've actually seen put people off using Macs, then it can only be good.
