There's a weird twist of fate lately -- I had a lead on a Rabbit base station and handset recently that I'm importing into the US, now this discovery? ;)
I already collect weird "personal cellular" stuff in my house -- probably one of the only running PHS home phone base stations incl. data, a bunch of NTT Personal handsets, and now this Rabbit.
It'll be very fun to make a call from a PHS handy to a Rabbit handset and vice-versa for probably the first time in the world very soon...
