The Web or Desktop?

That is always one of the first questions I have faced while developing any applications. Its sometimes so hard to get a satisfying answer. Each approach has their own benefits and drawbacks. The reason I am writing this post is after seeing this application being developed at Google summer of code. Nice project, but I don't get it. If you can sync data from Google reader why would you want to start up another application (which is probably not installed) and then sync all that data. This shows the power of internet apps over desktop equivalents. Again, when managin data on your computer comes into question, the best solution is usually a desktop app. Take for example, Amarok for music management. Maybe the next step would be to create hybrid softwares. Making data present on one system "present" at every other system accessible to you. I have my music spread out on various systems (at home, at lab). Sometimes I face the problem that some song (which I am dying to listen) was on the other system. It would be nice to see an app which can "sync" this sort of data. Probably extend it to songs on the internet and all other kind of data. One click to access anything anywhere. This idea has been in my head for a while. If nothing of this sort exists, I shall make one of my own during summer.
