Keep in mind that when we got updated from 2.1 (Eclair) to 2.2 (Froyo) there wasn't a lot of noticable changes, just under the hood kind of changes. The update from 2.2 to 2.3 will probably be very similar, in that a lot under the hood will change but the UI will remain, pretty much in tact. The EVO 3D, in addition to having the next gen HW, will come with a totally new UI. These two factors alone will have a lot of people jumping ship, unless they are rooted and have access to the newer UI ROMs. With Radio Shack hosting a trade in program that will get EVO owners into an EVO 3D for $99, it's almost a no brainer.
