Considering tablets are still be sold with 1GB having "only" 2GB isn't the problem some portray it to be, having said that this is priced way to close to other stuff that's a lot better, namely the Tab4 plus which has been available for amounts close to this. I'd buy a used A10-70f For £50-60 more than adequate for most users and save the rest.
I thought the Tab4 plus was this price recently?
How does this compare to the Amazon fire 10 HD?
Way too expensive to be limited by 2GB ram and Android 6. Even if there is 7 available now, we are on 8 and there's a fat chance this will ever get it. If I had £160 in my pocket, I'd be looking at a second hand Tab S2 9.7" for the extra ram and OLED screen.
If I was buying a new tablet I would aim for 3gb minimum ram or it will soon be outdated.
