I bought a new construction (I wasn't specifically looking for a new construction so it was already done when I got to it) and was really disappointed to see that:

- no conduit in the walls - no ethernet in the walls - coax to every room but it all terminates outside the house

which I'm sure meets most people's needs but was annoying for me. And it would've been so cheap to do it "right."

So I'm relegated to relying on the fact that I have very conveniently located unfinished half of basement and garage where I can do lots of cabling and just pop through the wall right at the end.
