Hi sorry. I know this is probably an easy question but I am new to all of this. I currently have my whole house wired. I currently use 2 iPhones and a few laptops (Windows) in the house, I will be buying an iPad next week and was just wondering. Is the AirPort Express basically a router? So when I set it up I will then have a wireless connection and be able to use it with my iPhones, Laptop(s), and my iPad? If that is the way it is, what are the pros and cons to this device?
