Convenience over all else is what 99% of people are doing.

That being said, I have an old LG Tv (pre-android, forget what they call the os), and I never connected it, opting instead to hook up a firetv stick .... (who knows what bad crap they might be up to btw).

But the point is, we are a minority, most people go the path of least resistance.

2. Convenience

3. Cheaper than buying an Apple TV et al
