Developers making apps for multiple mobile platforms -- iPad, Android, Playbook, etc. -- can use Adobe Flash Builder for that purpose. From Adobe's product website: But Adobe's product announcement this weekend gives a different story. Adobe used the native tools for their iPad and Android apps. Even though it should have been faster, they didn't use their own Flash Builder for making their multi-platform Photoshop Touch app. Adobe's actions speak louder than their [marketing] words. Why didn't Adobe use their own tools for building and deploying this product? For product developers targeting multiple tablet platforms, when does it actually make sense to use Flash Builder?
