Here's a pro-tip:
Don't shop for a "smart" TV (ie, for the apps), just shop for a TV. Concentrate on the important features: the display, the colors, the definition, getting sound, etc.

You can always plug a dedicated device into it to deliver what you want (Roku, Amazon Fire Stick, Xbox, Playstation, soundbar, surround sound, etc). That's why they give you multiple ports, use 'em!

Plus, the "smart" tech that TV manufacturers build into it is mostly an afterthought, and the apps are usually the first thing to go obsolete over time (the company can choose to stop supporting the service on your TV).

We use a portal tv and bought one for the inlaws a year ago and we love it. Yes it can have glitches with audio but restarting it fixed our echo issue when it happens. It's not perfect but it definitely has changed how we are able to spend time with my in-laws who live in CO while we live in NC. With us welcoming their first grandchild it's been amazing so they can see her grow basically daily. We love this thing. Again not perfect and I wonder the same thing... Why are other companies not creating tv add on hardware that does this but I do really like that this one does. And for $80 that's a steal. We had issues and FB did replace ours when it had a manufacturer issue and we were so lost without it for the couple of weeks it took to ship and get a new one. While audio issues are a thing (echos) the microphone is phenomenal and worth the trade off of when it acts up. We basically have an echo issue the first time we use it in a day and have to restart it to make the echoing stop but after a restart it is usually fine (and sometimes this doesn't happen, we have an older Samsung TV so I suspect it's the tv issue). My in-laws do not have this issue only ours does. We aren't currently using a sound bar but I did get my husband one for Xmas so we will see if it's an issue but if I have to turn it off to use the portal I don't think that will be too big a deal to be honest. While I wish they would improve the echo issue overall I'm super happy and my whole family uses this so much, it made the pandemic not nearly as bad and keeps is close with family that lives far away, but has even been awesome for family close by who just want to see the new baby for a few minutes here and there so honestly I would recommend it, the problems are far outweighed by the benefits. I just think of it as a beta product and deal with the issues as needed, granted I am fairly techy but I'm using it with people who aren't and they are fine too so 🤷‍♀️ More on reddit.com
