Good. I do the same.
Example of just two usages:
* dynamic port assignment - torrent app. New (random) port is forwarded on the router every time it starts. Port is immediately closed when it's done.
* almost static port assignment (I may change it time to time) - SIP server, FreeSWITCH. Achieved convenience is - I change it in one place (SIP server's configuration) only.
Again, IT life is not simple like black and white. It may bring you benefits and desired automation, but one has to learn how to use it safely (because there are always people, who want to exploit everything at their disposal against gullible and naive). Another
controversial for some example - I use actively ActiveX without security problems. Or, JavaScript is always on, whatever site I visit (Flash, on the other hand, can be started on my demand only and BTW, on all my computers its elevated privileges are removed, search this forum for my posts how to do it). And at the same time, I don't run any AV products all the time. I simply don't need them, because I do what you're doing -- practice safe hex
