Mine showed up yesterday. I ordered late during the Prime Only sale, and it originally said Jan 5th, but it got bumped up a few weeks - I guess the elves made them faster than expected 😀
We already have a number of media streaming/consumptions devices (2x AppleTVs, PS3, Smart TVs, XB, iPads, etc.), so this was kind of an impulse buy, but for $19 I figured it would be handy for _something_, at the very least fun to tinker with 😀
So my initial thoughts so far (only an hour or so of use and setup).
When these were first announced and it showed the power supply was USB via a wall wart, I hoped it could be powered directly via USB ports on the TV, though the power output on USB ports tends to be inconsistent. Well, I set ours up this way, and while it did actually throw up a warning about the USB port, it still started up, configured and it worked just fine.
Configuration (after the painful and way too long intro movie ... skip option[?]) took no time - it found our network, u/p entered and its up and running. They come pre-configured for your Amazon account you used for the order, kind of cool, one less step - unless, of course, youre like us and my account isnt the prime account, so I had to reconfig for the wifes (very easily done).
Like other folks have mentioned, the UI is fast, theres little-if-any latency, the remote doesnt need LOS (not sure if its a proprietary RF or using BT[?]). Overall the UI design is fine, its not like much is needed in order to show lists/icons of content, select, toggle a few options.
The PQ seemed a little subpar, now granted the HDMI port Im using wasnt as perfectly dialed in as the main port (we need a single HDMI in via a Pioneer AVR), and in actual use Id probably connect the Fire Stick to an HDMI port on the AVR as well - but Im wondering if the power warning means its running in some kind of limp mode, maybe not getting the full bandwidth[?] Could also have just been the connection last night, Amazon, etc. Ill have to do a back-to-back test vs. the PS3 (which is how we consume Amazon content downstairs).
Overall, its solid, for the price - factoring out the need/want for iTunes media consumption - its stellar, and its a complete, works-terrific-out-of-the-box experience.
