I still like the themes better than the persona textures, but some of them aren't so bad.
So pages do seem to load up quicker on some sites I've historically found to be a bit slower on both my desktop and my netbook (eee 900,XP, 512RAM). Certain sites that stream video seem to stream much better on my netbook on higher settings than before, which I didn't really anticipate, so I was pleasantly surprised. Couldn't get hulu to run any better though, but improvement is improvement.
I can't wait to see what HTML 5 can do. I was an avid supporter of Flash until Adobe took it over, and it's becoming spottier every year since.
My 2¢.
