It supports many online services as well, but unfortunately no Prime Instant Video. I have yet to see a box that offers everything I want: Local and network media playback, Netflix, Prime.
However, I wish the WDTV had better specs and UI - it can be a little clunky.
Roku is close once you use Plex. You get local network playback + Netflix, Prime, Crackle, Hulu, Pandora which is what I want. The video quality, performance, bugs, and gaming support of the Roku suck though. I keep swapping my Roku for a Chromecast and back again.
I'd like a box that supports Prime, local network playback, and casual gaming/emulation. If Amazon would have released a Prime Video app I'd switch to some of those cheap Android PCs on an HDMI stick by now but they've been holding out probably to use as a carrot to get people locked into their app store.
I hate having to side-load apps but if I can on the FireTV and get local network playback working I very well might buy one.
Edit: Looks like it will have Plex and Miracast support.
I'm on the verge of doing the exact same thing. On that plan are you able to use any of that data for tethering or mobile hotspot? A customer service rep said you can use all of your "up to 5GB" 4G data for tethering if you want, but I found that a little hard to believe.
Tangent: How on earth do product blogs not have a link to their product page? Nowhere is there a link to feedly.com in their header or sidebar, I have to manually edit the URL. Ridiculous.
Even if Apple was the first company ever to have a disappearing scroll-bar on a mobile device, I'm amazed something like that can be patented. To me it seems like a common sense evolution when shrinking things down to mobile proportions.
"You know there isn't much screen real estate here, so lets get rid of the bar, and only show the scroll head when you are scrolling. Good idea!" Why should someone be allowed to patent that?
It's like the first website ever to say, "We really have a lot of menu items here... I know, let's group them into sub-menus that 'drop-down' when you mouse over them?" Boom, drop-down menus are now patented, pay up if you want to use them in your website. Sure there were drop-down file menus on computers before this, but I'm the first one ever to do it on a website.
Can someone explain why the two are nothing alike and I'm an idiot for feeling this way?
