I currently have the AirPort Extreme as a wireless router. I had it for close to two years now. I also have an AirPort Express that I bought shortly after release. I used it as a ethernet-to-wireless adapter for my PC and my game consoles. But I've sold off my PC, and I no longer play online with my consoles. So I'm wondering, which one should I use as a router? The pro with the Express is that it's very small. But I'm wondering about the signal strength of them? I have only three users, so the 10 users limitation is of no concern to me.
