You're right about the "feel" being off, even if the actual page turn speed isn't that much lower. I couldn't stand how sluggish reading seemed with the new firmware, so ended up downgrading.
I don't want to complain too much though, since the Touch is a much better product now than the buggy mess that launched. It's nice that they're supporting it so well.
Even easier than this is downgrading to the previous firmware.
