We just got EZ pass this year in Maine, CJ. Works like a charm. In fact, a couple of weeks ago I drove down to NYC, and the Hampton toll is the only toll on the whole trip I had to open my window for. Glad to hear NH is getting it also.
FYI, I spray painted my EZ pass black, including the two velcro mounting strips they included. Place it up behind your windshield rear view mirror. You'll never notice the thing from inside or outside that way. Make sure to put a piece of masking tape first over the part that has serial # information, then remove after painting.
I love stealth stuff....
