I know about that option, but the price per port, including RJ45 transceiver, is huge compared to 1 Gbps ports. Also it is limited to 4 ports only - even for home use it is not enough, all the switches in my home (more than 3) are 8 ports and above.
Well, the idea is that you only wire trunks, wifi APs, and SANs w/ 10GbE, and light a select few wall jacks that matter.
~$120 per port (assuming 309s, the recommended interleaved spacing, and amortizing the switch cost over # ports) isn't very expensive if (a) you need the capability & (b) already have copper in the walls.
Drywall finishing along will run you that much. :) But yeah, new builds should definitely be fiber.
