That saves you from some potential issues but not others. My google search magic isn't working, but there was some manufacture a number of years ago who's TVs were crashing because they'd save up massive amounts of data to upload and either exhaust all their memory or fill up the disk because it never connected online.

Also, if you live in a household you have to make sure every other person behind that TV doesn't connect it to the net at some point for some reason.
