I run a web app and am happy with it. Advantages: - no update process - support is easier, because you don't have to dig in the users specific setup - monthly subscription model might be easier to accept for people, if they don't have the feeling of "owning" the software like with traditional desktop apps - no multiple platforms (although people want apps, but at least, you don't have to also provide Linux and OS X versions) Disadvantages: - no offline mode (some people want that) - some people want the feeling of ownership and privacy I think as a one-man business, it's easier to maintain a web app than a desktop app.
