Would you choose wireless highspeed or aol broadband?

I have had aol dialup since I have had my desktop pc. The pc still works good so I just want a faster service. I am considering going wireless. Not sure if to stay wired and go with broadband or to with a wirelss highspeed service. Hoping I won't regret getting rid of my aol dialup servcie that I have been to comfortable with all these years.
