From what I've read in other threads, Skype probably won't see the PB anytime soon, Android or Native. I could be wrong cause I don't know anyone who knows someone who heard from a RIM employee.
Sounds like Video Chat is being upgraded to work much better and work with other avenues.
As for the question of the thread, I would go ahead a download and install the beta. I've been using both of the betas and have not had very many problems. both seem very rock solid for what I'm doing with the PB.
