So I already have one FireTV that I bought pretty shortly after it came out. Because of that I was able to prevent it from updating and also was able to root it and unlock it. I've been very happy with this device but I'm looking to acquire a second device and that's my problem. With the state of the FireTV now it seems that it is unrootable and potentially brickable with the way Amazon is treating it. Also, I'm concerned that the future may hold a device that can't have apps sideloaded as well. My primary use for the device is Kodi/XBMC, Netflix, and Plex, though I do have prime and occasionally use prime instant video as well and I pretty much prioritize my use in that order. I suspect if I went with something such as an Amlogic M8 or some other android box that I'd have to give up the Amazon services.

So I guess my question is, how does the FireTV hardware compare to the others? Is it a lot better than something like the M8 box? I'm not really a dev, though I'm extremely comfortable with android flashing and such as well as linux, so I'm also wondering are the devs optimistic that they'll be able to hack around Amazon's attempts to block us? Or is it looking more like a lost cause? I noticed work being done on a CM12 port but if I buy a brand new fire tv that can't be rooted then it would seem I'll be limited in what I can do or flash with it.

I'm looking for opinions or feedback so all thoughts and suggestions are welcomed. Thank you!
