After spending a few hours in the car with this since yesterday, I can't believe how much better than stock it was. I imagined it would be a bit better, but not this good. The touch screen is actually responsive now. I don't have to keep hitting the same thing over and over again to get it to register, and it's FAST compared to what it was. Navigating the SD card interface is WAY faster, which is awesome because that's where all of my music is kept.
Props to the OP for this. I'll be seeding it all day as well.
