Is upgrading to ios 5 Beta 6 worth it?

[Mikedb94]

I am running version 4.2.1 on my iPod Touch 4th gen and I was wanting to know if upgrading to ios 5 is worth it, how buggy is it? How will the performance of my iPod be affected? And if I was to jailbreak would I be able to use my favorite apps like Grooveshark? I understand that the jailbreak is tethered and im fine with that, I just want to know what kinda waters ill be swiming in ya know
Thank you to anyone that helps me with my issue.

A lot of jailbreak apps are not working on iOS5 yet so if you want to jailbreak it you may want to hold off updating until iOS5 is officially released.

+1 Personally, I wouldn't do all the work to install something that expires in a month. I love leading edge technology, but stay away from the bleeding edge
