The largest change you’re going to find here is the complete disappearance of the long standing three-button Sense launcher bar normally sitting at the bottom of your display. Instead you’ll have a completely separate app drawer and phone keys. There’s a brand new ability to add and remove homescreens now, and Widgets have been tweaked as well. Smells nice, doesn’t it?
What we’re seeing here is an upgrade to what yours truly considers one of the better out of the box user interfaces delivered by a manufacturer since Android began. Sense 3.0 has treated this team quite well, this upgrade to 3.5 is set to be the buffed-up and much more magical version of a winner. Expect to see this user interface on the HTC Holiday (aka HTC Raider), the HTC Vigor, the HTC Bliss, and maybe even the HTC EVO Design 4G. Be there!
