Mi Box Specification
The 4k problem is actually the lack of content. Streaming 4k is not a great option, because my internet cannot handle streaming it. Downloading it takes forever... and not to mention the sheer takes up too much valuable disc space on my harddrive. 4k discs are being sold, but are limited to certain popular titles and at an extra cost. Discs are priced at usually at $30, which is $10+ more than Bluray discs. Plus, unless you got an Xbox One S, 4k disc players is an added $150 or more extra cost.
Basically, it's a chicken and egg problem, but eventually 4k is the future. For collectors, the steelbooks and special packaging are only available on Bluray, so they're not migrating any time soon.
So why would you want a 4k TV? Let me break it down to you: the image quality is much better than a standard 1080 screen. It's not just my imagination, because the pixels look smoother/sharper because the image is upscale on the same display size. The smaller the dots, the better it looks... but only if you have really good 20/20 vision (or look closely at the display).
The other cool thing about my Samsung set is that it comes with apps, so if you're watching TV, you can click on the extra icon to see the latest weather or play minesweeper, etc. Although you can install apps directly on the TV, the Samsung App store is severely limited.
My only 4k streaming box options right now are: Roku 4, Chromecast Ultra, Nvidia Shield, or the Mi Box. Having own the Roku 2, I was not impressed with its inability to turn off or that it does not support multiple audio or even something simple as subtitle support.
As for the Chromecast, you basically need an Android Phone (which I currently don't own), and the Nvidia Shield is just too expensive ($200 for the base model and the remote is an extra $50, and the stand is $30)..... so that left me with my only choice: The Mi Box. If you aren't familiar with the Mi Box, it's a $69 Android TV box sold by Chinese company Xiaomi.
When you get the Mi Box, I suggest getting the Kodi app (formerly known as XBMC) so you can stream your local DNLA or add streaming video playlists. Kodi is really just the best app, I've used it on various platform. It will play everything, and it does multiple audio and multiple subtitles. It's really the only video player you need.
