Why Twitter Clients?

Call me ignorant, but with a fast-loading website, I don't see the need for desktop Twitter clients. I update my status probably a couple times a day and I don't find it too difficult to update it quickly. My current setup:

- Rocketdock with a Twitter icon

- Google Chrome application shortcut, saved password

It works beautifully. One click access and I can update my status quickly... why TweetDeck? I might start using this gadget though.
