Anyone done a performance comparison? I have both, but haven’t had a chance to run any tests yet.
Well, run it then you lazy SOB !!!
We are waiting! 
Unity Terrain on mobile is fine if you are interested to limit to iPad2 only, cause other iOS devices for example won’t run with it anymore, the overhead of the whole phyiscs calculation etc will totally kill them.
T4M on the other hand works fine in such a situation
So you are saying that teh native unity terrain will only really work ont he iPad 2 and not, for example, iPhone4, 3G, etc…? If that’s the case, then I suppose it is safe to assume that it won’t work very well on Android either?
I would guess so, cause Android rendering is even slower than iOS on the same GPU due to the common driver quality.
If its usable also depends a bit on what you do. But if you have some players / AIs walking around on it with physics, you will pretty surely not like the numbers Physics.Simulate will write into your Profiler window.
