A lot of people will regret rooting when patches and updates come out. You will need to be prepared to do more footwork during those times.
True... being a tech nerd.... stuff like that doesn't phase me in the slightest. The only thing I have to watch for, like you say, is an update that shuts something down. But I'm not really worried about that to be honest. T-Mobile doesn't seem to care all that much about such things (and they are the only one in the world that had LG unlock the bootloader for them)
