My experience:
Performance: about equal to the WGT line of wireless routers, with the same caveats (lockups, lost connections, flubbed DHCP leases, etc.) but better wireless coverage. Supposedly there's a magical beta firmware that makes it more reliable, but I can't be bothered to flash a router that's sitting on a shelf gathering dust.
Other Stuff: stupidly BRIGHT UFO dome lights, need a torx driver to open the case and void your warranty to turn them off.
