I looked at some of the android boxes last year as most of my tv viewing is streamed, but at that time the android boxes were more expensive than they are now.
Yep I could see it being a cord cutter, I know a few people that have switched from Sky to the likes of AppleTV or Roku boxes.
I'd just swapped my ipad for a galaxy tab, which practically made my AppleTV useless hence being in the market for android type box.
In the end I went cheap - £15 for a Now TV box which included a three month pass. When the 3 months was up, I made sure my direct debit was cancelled and now use it just for streaming with the standard non sky apps. There isnt an app for Kodi, but there is one for Plex, youtube etc etc. However I tend to stick with the likes of iplayer, ITV hub and All4.
