The Buying process of Bitcoins will have to be made much more simpler than it is at present. All indications point that the process will get more streamlined, so buying bitcoins will be an easy task.
In most countries (US included), companies that trade Bitcoins onto the local currency would be regulated. More exchange companies will mushroom.

Yes I agree simplification the usage of Bitcoins would make this currency more popular and may company will use and be recognized, at present it is quit complicated to those people who are not so familiar with the process, but once it become simple and they can realized how simple & versatile bitcoin is maybe there might be a paradigm shift in the market place.
