Google WiFi looks like a total disaster to me, all because of the serious limitations it has - the most significant being that remote AP's have to be cascaded via Ethernet which is a totally stupid restriction to have.
Without naming names it was interesting to see quite a big NZ tech entrepreneur get all excited over the Xmas / NY break about receiving his Google WiFi and his experiences were posted on twitter. He'd given up after a day and was looking for a better solution.
