> This brings up another question. In iOS, there is no good way to charge for an update - user buys once and gets free updates for life. Will they change that with the OS X App Store?
The solution for this on iOS is the same as on Mac or Windows - release a new version. From 2.0 to 3.0, a lot of companies will charge for the update. Do the same thing on iOS by releasing a new app entirely. This also lets you fix bugs in the old version for users that don't want to update.
The only thing missing in that plan is an upgrade price. Apple really needs to consider adding something along those lines.
