Mostly use Crunchyroll - sure, plenty of ports exist for sailors of the high seas, but I don't keep my computer hooked up to a television in my living room with a comfy couch. Watching anime on a couch on a decent-size TV is a vastly, vastly more pleasant experience for me than watching anime hunched over my laptop, and my smart TV (gotten for free from a previous roommate who was looking to downsize) let me have that experience with ease.
