Should I update my P1P firmware?

Last time I checked (probably a year ago), the sky was falling and everyone was up in arms about the changes BL was making. I read not to update firmware because ... bad things. None of those things really seemed to affect me at the time, but now I still have 01.07.00.00 on my P1P.

So now that the dust seems to have settled, do pros outweigh the cons of upgrading firmware?
