I am probably the last kid on the block to get 4G/LTE but the speed still impresses me. Even with a not so good 3 out of 5 bars connection I get speeds way beyond "full rate ADSL" (8 Mbps downstream, 1 Mpbs upstream) and that was an impressive wired connection not that long ago. And I get it wirelessly. On a cell phone network. At a reasonable price.
The Rikomagic MK902 is a quad core Android set top box for any HDMI equipped TV. The only thing it does is allow you to run Android applications on your TV - but with about a million applications available, that is no small thing.
Rikomagic (they also go by the name RKM) is a Chinese company that made the popular and much copied "Android on a stick" MK802 back in 2012 - a device that helped start the Android set-top-box market.
It is not the most stylish watch out there - far from it. But beyond that, it's actually a pretty good smart watch. The real question is how long it will take before it becomes outdated by something better. The grayscale display and the wide bezel will eventually look as '70s as the general shape of the watch already does. But for the time being, this is almost certainly the best smart watch there is.
The "A-Link SmartTV" box is one of many low price Android devices on the market now intended to be connected to your TV. Some are even shaped like USB memory sticks but instead of a USB connector at the end they have a HDMI connector, allowing you to just attache your Android device to the back of your TV.
