You can make it work, I can even have good animation performance with css3 on the iphone 3gs. Animating one or 2 items works well, Things you need to be careful is too much animations at the same time & accessing and modifying the DOM while you animate, you need to "block access", something IOS does natively it seems. But for Android that's another story, one device it's goint to be pretty good, on another it's complete crap and you need to deactivate animations all together.
