After the update, there are a bunch of updates needed in the Google Play Store. HTC BlinkFeed, HTC Gallery, HTC Sense Input, HTC Sense Input-Z-H, HTC Sense TV, HTC Service Pack, and Zoe Beta. These are pretty big files. I will let you know if I notice any changes. But, like dfran1 said, the phone feels quicker and more responsive. The interface looks cleaner. Web browsing on WatchUSeek site is much improved. But, there is a slight lag as the browser loads the page. it is maybe 1 to 2 seconds longer. but, the browser handle Desktop versions of site much better. The other thing I have noticed is a lot of changes to the camera app.
