There are also a fair number of soho [wireless] routers with telnet enabled by default. I guess that's partly due to memory footprint, or assumed memory footprint (dropbear being fairly small), by the manufacturers, and partly due to windows not having a ssh client by default, whereas every major OS comes with a telnet client.
