They say the Sense UI thing is more deeply attached er whatever to WM, so it's not like the touch flo today screen item where you can turn it off. Should be interesting to see someone getting titanium working on the leo.
I'm all for HTC skinning WM on their own, but they should leave the option on the table to NOT go with their skin should the user decide.
