That depends--are you on the AU yet? If the answer is yes--then the IP probably isn't worth it right now. I am on slow ring for my SP 4 but it is my 3rd device behind 2 more powerful computers, so I can afford to wipe it and reset if I have to--and that is possible that it may come to that. There are hangs and freezes right now, and, at least on slow ring, no real new features to speak of.
When more of the RS2 updated features start coming out, it might be worth it to try some things early.
As it stands right now, if you are already an AU user, it wouldn't really add much--and if this is your main device, there will be bugs, hangs, freezes, and issues, so you probably don't want to deal with that on your main rig.
