It's not even close to what you can do on a PC. Here's a link about that:
I'm guessing here you want the full browser experience you get on the PC but on the TV? That's what most of the complaints seem to center on. As there is no PC in that, you get an "appliance" internet experience.
There's also issues with pushing around Google to get they YouTube to work with keyboards. We have prior discussions about that but even Samsung can't seem to push Google to supply a good version. Here's a link about that:
The apps are complete for an appliance. If you want a PC experience you need to consider adding a PC. Some folk explode over this but as there is no PC in the TV, it can only do so much with it's limited ram and CPU.
This is a no-brainer, but I was extremely surprised my recently purchased UN40EH5300FXZA wouldn't recognize the keyboard in the YouTube, Netflix, or Amazon Instant Video apps.
There's nothing smart about that. What there is is a huge usability / customer dis-satisfaction issue.
Yes, I've paired my Android Tablet to the TV and can search for and play a YouTube video on my tablet, to have it displayed on the TV, but, that wastes bandwidth, and it isn't perfect. It's in some cases quite buggy.
Yes, I've also tried to use a port of the Samsung Smart View app on my tablet (because I don't have a Samsung phone - someone ported it and the .APK can be found on the web), and while it, like the pairing option above provide functionality, the keyboard on SSV doesn't pop up in those apps.
Close, but not quite.
The Web Browser on the UN40EH5300 runs out of memory... Someone is doing extensive testing of this stuff, yes?
Samsung needs to push its partners hard on behalf of its customers and provide some basic usability and operability improvements to these apps.
You can sense the potential for "smart" here, but what is passing for quality, "fully engineered", compatible or integrated is very disappointing.
Samsung, please step up completeness in productization.
