Do you need more than 1 Gbps from your wired network to your internet connection?
Otherwise you may have 2.5G or 10G LAN, or even fiber inside home like some [1], and only have to use the slow 1G to hit the internet from that. (Another 1.5G of bandwidth is available over WiFi.)
If I decide to get 2 gigabit internet, yes (and my local phone and cable companies both offer it). I also run a server in my basement (on ethernet), so not being able to get the entire bandwidth on it would be disappointing.
While it's cool that OpenWRT has their own routers, I feel that this one is not for me.
