They said the same thing about 40G but hey, I've loved it for bridging the gap between my two (10G and 100G, respectively) Mikrotik switches. You can have a dozen Gigabit ports, as well as up to four true 10G devices on your aggregation switch, and neither would be bottlenecked by traffic to and from the backside. This has been a massive boon. However, when it comes to 2.5G, I struggle to find one good reason to use it; such a tiny step-up in bandwidth, and for what?
