Yep, that's true. I have an old netgear 802.11b upstairs, and my Powerbook doesn't manage to lock on it while downstairs. N800 does, and to my astonishment also reports 4 WLANs belonging to neighbours of mine, from inside my house (which has a copper roof), and which are 150-200 mt far. Impressive. Kudos to the little beast :-)
