IOS 5 Jailbreak - Still Worth It?

Today, Dev-team released Redsn0w 0.9.8b1, capable of jailbreaking the latest Apple operating system for mobile devices, iOS 5 (beta).
This is a tethered jailbreak which means you have to connect the device to a computer and run Redsn0w to achieve 'jailbreak mode' on it.
With all these improvements added to iOS5, is still worth it to jailbreak your device?
I used to jailbreak my iPhone in the past in order to obtain a higher level of customization for it, have access to options that were not available in the official iOS, adjustments that could improve my iDevice experience after all.
Many of these "improvements" are now available with iOS 5, still missing some.
In my opinion, iOS 5 is a big step for Apple, which seems to have learned from the jailbreak community for the benefit of its customers. Wish that many companies do the same (eg, Sony).
Some characteristics that helped Apple achieving this step are:

    Notifications unified
    Phone-to-phone messaging
    Newspaper / Magazine subscriptions
    Advanced System reminder
    The whole system integration Twitter
    Quick-access chamber
    Photo Editing Tools
    Tabbed browsing
    Reader views
    Scope text email
    No PC setup / upgrade
    Wi-Fi Sync
Not many of the mobile operating systems today come with so many features that make it one of the best iOS mobile operating system in the market today.
However, the question remains ... is the jailbreak is still a necessity?
Many users say "YES", jailbreak is a "must have", probably because they are unaware of what the new iOS can do, some may still have favorite applications that are not available in the new iOS (eg BiteSMS), but many stay away from jailbreak from now, because most of the features that are now jailbreaked by the operating system.
In the past, jailbreaking was considered illegal, the device warranty.
A few years later, they all become legal, as long as you are not installing / using paid apps for free using the jailbreak tools.
Today, jailbreak means more than allowing non-signed applications to run on your device (Apple requires each application running on your iDevice to be signed with a certificate, so have better control over their devices and applications running on it), became a cult.
We still have to wait until the final version of iOS 5 is released, but take a look at the beta version, iOS built features that no other mobile OS can be proud, so iOS 5 one of the best versions that Apple come with.
