will you use the tablet for playback?  at home? or remote?

I'm asking, but don't really have much of an idea.

I did have an apple ipad, which I used to play movies over plex when I was in hospital. But they are very expensive.

Yes it's for using at home so direct connection with the nas.
I use it when working on the treadmill.

If your tablet is working fine now, & just want something newer, I would just get the same make but within your budget. 

Hopefully someone else can help your more.

No that's the issue, I can't read x265 content or high bitrate files.
I was just asking if there was something to avoid and / or a best buy tablet for Kodi.
