columbia does provide free dial-up access to all account holders. but in law school, you'd be an idiot not to have high speed at home, if you ever plan on doing any studying there.
also, for three of the four years i worked at columbia, i lived on b'way at 107th. if anyone's interested, pm me and i'll give you the landlord's info. seven story elevator building. studios from ~$1000, 1 bedrooms from ~$1450. great location, directly across from absolute bagels (far better than h&h), with a laundromat on the first floor and a liquor store next door.
