I have P5, and with the Service releases, it now works perfectly fine. Nobody got burned. Singed, yes, but not burned. There is nothing P4 can do that P5 can't. And P5 adds a lot of capability. Believe me, I was VERY unhappy with P5 at first. But to be fair, it's not that bad (now). Of course, they have a lot of things to fix, including everything on Phantast's list and then some.
