I need to get mobile broadband account for my laptop. Anyone of have suggestions of which service is good in this area -- or which to stay away from.

Broadband as in mobile wireless? Id say Verizon. It works in the Metro.

yes, thanks. I need a wireless card so I can get on the Internet from my laptop

I have been using Verizon for about four years without any real issues. I take the train to NYC a couple of times a month and the service is consistent the entire trip and I have even had good results a couple of miles offshore.
