Well, creating a web app will give you a larger addressable market and more flexibility in adding features in the future. A downloadable app will let you tap into the billing services offered by the Apple AppStore for Mac and use the native features of the computer (including off-line functionality). I would start by answering questions about what your application will do and then choose the right platform for delivery: 1. Will the application need to work offline? 2. Will it be multi-user or single-user? 3. How often will you update features? In general, it's always better to build a web app than a native app. Exceptions would be for products where network access is not guaranteed (mobile phones), products that need features of the device (skype) or something that is too complex to build a web based user interface (photoshop). Hope that helps.
