Like some others have said, the new release feels much less responsive than UD 8.0. Prior to install, I did a full wipe (twice). I left the stock UD kernel and turned the speed up to 800 using the built in control.
This only the second ROM that I've added to my Droid. I installed UD8 a few days ago then tried out this one. I don't know how the Droids are compared to a Blackberry, but whenever I would install a new OS on my Blackberry, I would have to give it a little time to settle in.
I was having problems with 1.0 being a little sluggish at first, but after a couple of reboots and letting it settle in for a full day, it's great. Very quick and responsive, and I'm using the stock kernel. Just give it a day or two and then see if you feel the same...
