Two advantages: - Deliver apps over remote - Superfast keyboard interaction (forced) One big disadvantages: - Limited graphics and advanced UI component support I would say the optimal UI is a Keyboard driven normal Desktop app. An app that can take full advantage of graphics elements of a desktop app but is lightning fast to interact with thanks to that it's keyboard driven. Very few people build apps like that though. Sure there are keyboard hints in many apps but they are usually not 100% guaranteed to cover all cases and are sometimes an afterthought.
