I will say, I really like the UBNT ONT, and I've been thinking of offering it as a premium option because of the display. Having the ability to show usage easily is very nice. I just feel UBNT missed the price mark here, and missed the opportunity to do something big like ngpon2 with 40gb/s capacity capabilities. That would have rocked the manufacturers.
