Finally I got my MK808B this week and following are my initial impressions:
1. The USB stick packing says "MINI TV" and there is a hologram with name "CozySwan". Seems the vendor is CozySwan. The build quality is pretty impressive for the price.
2. The device has Android 4.2.2 out of the box. The installation is pretty easy, attached the device to the TV through HDMI port and voila the TV has become smarter now. The device came with few pre-installed apps and thankfully with the Google play app and support.
3. I configured my wifi router which is around 30-35 ft away from my TV with brick walls in between and as expected the signal was weak. I could install few apps from the Google play but I feel, I need to move my router in the living room or at least in the center of the house to have good connectivity in all rooms. My Laptop never suffered weak signal but then as this is a pretty cheap device it struggled with weak wifi signal strength.
4. I tried using the XBMC s/w and I am pretty much impressed with it. Now all I have to do is to prepare my data structurally on my Laptop and share it over wifi so that the XBMC on this device would stream it on TV. It can also use the locally (to the device) connected HDD/storage. I am not sure about how much HDD it can access.
5. The video quality is superb to say the least. As the Audio and Video travels on the HDMI, there are no messy connections. A single cable takes are of A and V. I played "The Hobbit" HD movie stored on a USB drive attached to this device and it played it flawlessly. Of course the quality of the movie is too good and the device did not play any spoil sport. One observation I made is, while the "Screen output" was set to default 1080p, I could somehow feel a 0.5 secs delay in the picture speed. Since my TV is HD ready (720p), I changed the screen output to 720p and voila, the speed was corrected automatically. May be this has to do with downscaling of the 1080p to 720p and thus a very very slight drag in 1080p mode. Please correct me if I am wrong.
6. This little thing scores big time on convenience (Of course all similar products). I have a 2 year old DVD player which would not play mp4/mkv files and thus kind of useless for me since few days. This device will now take care of decoding the mp4/mkv files and I dont need to spend on Bluray etc players. Since I would be in the market for AVR, this will be a big plus for me. I guess the AVR would take the HDMI output of this device and then further process the audio as per the encoding. So theoretically, I can see the movies in HD quality and get the 5.1 true surround (if the movie file has it) when I would connect this device to my AVR.
7. The only remaining thing in my setup now is the remote keyboard and mouse. Since I have a tight budget (Thanks to wifey), I would settle for RC11/RC12. Overall, I wanted to spend as much less as possible. I bought the MK808 for 3200/- and I hope the remote would be in 1500/- range. For around 5K, this is going to serve me well.
8. Ajith and others: Thanks a lot for your inputs and helping me out. I hope my initial impression would help another soul treading this path.
