the best thing about root is that the rom cookers will have the official 2.1 images im sure with root soon enough. I'm all for official too. I love checking out leaks cause it's fun, but usually ported leaks have bugs and instability. What I've found that works best for me is to keep it rooted on 2.0.1, but apply some minor mods that only root could do, like change the stock launcher to have 5 screens and to make home screen auto-rotate. I've also pulled in some of hte system apps like the 3d gallery which is cool. It seems that these changes are mostly safe and introduce very very few bugs. So I'm waiting for when the official update/code is released and I'm fairly sure there will soon be an official 2.1 rooted image for me to use to keep going with this.
