Finally got a chance to look at the new search page and it works fine for me and looks good! Oresumably you fixed some of the issues earlier posters mentioned. In particular, I did not notice any sluggishness as the opacity changes.
My only comment is that when the auto-complete dropdown appears, as you move the cursor over the dropdown, it changes to the I-bar rather than staying as a pointer. This might confuse folks a bit but I don't know how much control you have over that and I didn't check the coding to see if I could say anything more helpful.
