Got the Lemel HDMI stick in:
1. From pre-shipment conversations with them (Lemel via Newegg), it has a legit version of multi-language 8.1; they setup an account & switch it to English for you, so you don't have to navigate through the Chinese menus yourself (optionally, otherwise . Unlike the single-language version that came with the MeLE, this just says "Windows 8.1 with Bing", and sometimes when the system stutters (chokes a bit), the menus flash in Chinese (like the blue program titles). But, it is an activated & legitimate license.
2. It includes an HDMI extender (which was handy, since my multi-port test monitor's plugs were too close & I couldn't plug it in directly), as well as a USB cord with an A/C power plug. So you can use it off a built-in USB hub, or off an A/C jack. Curious to test power consumption with a regular jack, a 2.1A jack (and I think they sell 2.5A etc. A/C plugs), and USB power.
3. Gets hot. Not warm - HOT. Like hot bowl of the microwave hot. I don't think I will use this in production due to the heat generated, it's worrisome.
4. It's stuttery. The A/C plug-driven models are smooth; this model is stuttery. Like just putzing around the system can cause some GUI & mouse lag. It's not all the time, but it's enough to be noticable & annoying. I'll run updates & do the usual stuff to confirm it does this all the time.
5. Sometimes 1080p Youtube plays smoothly, other times not. The weird thing is it doesn't peg the CPU; it has stuttery playback at like 50% usage. So I'm not sure if it's not turbo boosting, or thermal-limiting the Intel HD GPU performance, or performance-limited due to the USB 5V power source, or what. But it's not an OOTB "minimum" experience of being able to play HD Youtube videos effortlessly every single time. I suspect it's thermally-limited since it seems to play fine when the stick is running cool, but slows down when it gets toasty after a few minutes of fullscreen Full HD video playback. Not 100% sure yet.
6. It is amazing that they fit a whole computer in this. Just bonkers really. And we just accept that it is what it is. I've been showing it off all day to coworkers and everyone is blown away.
Overall, for this particular unit, I like the concept, but we're a generation or two away from it being usable. If it had a 14nm Atom chip in there, it'd probably be a different story due to the thermal problem it has right now. The concept is excellent, however - most printers are wireless now, and a single Unity receiver can handle a mouse & keyboard (plus other devices), so that would fill up your USB port (unless you opt for a Bluetooth keyboard & mouse).
