Thanks Jim , I am not too up on this media box stuff either
Just pulled the trigger on a Bestland MXQ PRO , at 36 euro looks like good value
From what I gather , Showbox app streams high quality media only as opposed to Kodi , will steam anything regardless of quality
Showbox can be installed and streamed via PC/Macbook using an android API but for pure laziness , you can get an android box just PNP to you TV , the basic functionality is similar to your Sky box, pre installed interface , have what looks like a TV remote to navigate and select what you want.
Some of the apps on there have a similar interface to netflix, fairly idiot proof and saves me booting up,plugging in PCs to TV and no remote
For 36 euro worth a punt , talking to the guys in work, 1GB of ram(memory) is enough
