Agreed, the native apps look and feel much better. You see this even when you compare Android Gmail to web-based Gmail on the device. The former is slick, the latter is slow and clunky.
Yes, Google has been pushing offline webapps for years and years now, but this is still many years away before it becomes a reality. In the meantime, Android will continue to lag behind its competitors, who have explicitly decided to focus on the App market and are pushing developers down this path.
