What are the main benefits you get from using Tails OS?

Does it not become cumbersome to use the web for normal usage without persistent cookies, history, bookmarks, ...? If you save those to persistent storage (if that's even possible, I imagine Tails has safeguards against shooting yourself in the foot), you lose one of the main reasons why people use Tails.
