Nothing jumps out at me, but I am encouraging my brother to get the new Echo to replace his other Dot1 (I replaced the first Dot1 with a Dot3). I'll look for a trade-in for him as there is no hurry. His Dot1 doesn't understand him so well since he can't wear his teeth any more (hopefully a thing that will change). Doesn't have any problem with his Echo2 or the Dot3.
