I've just bought myself an X51v and thought I'd give my wife the old 50v.
I'm using AS 3.8 with my X50v and have been reading all these posts of people running screaming back to it after trying to run AS 4.x. I'm also seeing posts which state that the 51v won't run without going up. So now I'm wondering if I'll be able to get the two devices to play nicely?
Anyone got any clues about should I/shouldn't I install the upgrade and what I might need to do to get things smooth? :?
