Like the title says, I'm curious as to what devices you're using to watch IPTV. I personally swear by dedicated STBs and won't do any kind of configuration or setup for my customers on an Android box, etc. (I'll sell you the service but the setup and configuration is on you) because I haven't had great experiences with IPTV + Android (I'll admit that they've mostly been on a Nexus Player which isn't a great device for IPTV in the first place).
So what is everyone using?
Samsung TV (with Smartiptv).
