Socket ports below 1024 require the ROOT user id in order to establish a server. If you're building an application intended to go on random devices, you're not going to have any success opening a server on port 80. This is not an Android constraint, it's the way sockets have been in *nix for a very long time (if not always). It's a security issue to prevent malicious applications from spoofing a service on a machine that doesn't already provide the service.
